"Within sight of"...?![edit]

It seems to me that "within sight" is too easy, and dilutes the honor associated with this prestigious award.  ;) (Besides, there are certain graticules where practically the entire thing is within sight of a pub!) Then you run into the whole problem of: if your geohash location is on a hill or mountain overlooking the city, you can see dozens of pubs! Etc.

I suggest that the award be changed such that it is only achieved if the site falls AT a pub. I would say that the sidewalk in front of, parking lot associated with, beer garden, and similar "extensions of the pub" should also count.

I didn't update it, because I wanted to give a chance for discussion and, in particular, the author to consider. Ted 14:50, 2 June 2008 (UTC)

There is some precedent for the "nearness" factor, and I like the "within sight" limitation. Our hash yesterday was one block south of a pub, so I argue for at least that nearness to be included. Perhaps "3 blocks and you have to be able to see it" would be good? --Thomcat 07:14, 29 June 2008 (UTC)

Probability of landing in a pub?[edit]

Through some calculations, I've been able to deduct the probability of having a geohash land in a pub:

I got this by getting the number of pubs in a few countries (UK, Australia, Israel, China, France, Canada, Mexico, Argentina), getting the average and multiplying by 190 (Countries) for a total of about 2,000,000 pubs (Note: I used for this, so this is only for buildings with the word 'pub' in it's name). The average square feet for a pub is 2000 feet squared, so 2000 squared (4,000,000) times 2,000,000 (pubs) equals 8 trillion square feet of pubs around the world. The land area of the world is 1 and a half quadrillion square feet.

A 8,000,000,000,000:1,600,000,000,000,000 ratio equals 0.5%.

Umm, I think I did something wrong, my original calculations said 0.0018% chance which I think is more probable. If you notice what I did wrong, or if I'm right, please tell me. I just wanted to put this here before it goes or doesn't go onto the Pub Geohash page, but a 1 in 200 chance doesn't seem likely. I was writing this section after I did the original calculations, but I'd only gotten pubs from UK and Australia and estimated pub sizes. Please correct me. --The Man Himself (talk) 06:25, 2 March 2017 (UTC)

With over 500 expeditions, I've reached UK coordinates in sight of a pub a few times and in the car park twice. In the UK, pub pressure (pubs per square metre) is quite high. Most of the world is less densely populated so your chances are lower. On any single day, the chances are lower because I'm much more likely so set out if there is a pub at the destination. Have you calculated your pub area based on line of sight so the pub is in view of the hashpoint? I'm glad someone is taking this important topic seriously! --Sourcerer (talk) 07:18, 28 February 2017 (UTC)
Alright, I'll figure out the probability of being within sight of a pub in UK.

There are 48000 pubs in the UK and the UK is 243,610km squared, meaning one pub every 5 kilometres. I got some pubs around the UK (one in London, one in Illindrod, one in Leadburn and one in Crieff. There is only one pub in London because there are four times as many pubs in country UK than in the big cities.) and used Google Maps Street View to find out when the pubs went out of sight. In London, for the pub Cheshire, the distance was 300 feet away until you couldn't see it anymore (assuming you're on the sidewalk or in a car) but in the three country towns the distance was further, with an average 570 feet away due to a lack of tall buildings. So, on average, the distance until you can't see a pub is 435 feet. if we draw 435-feet circumference circles around every pub in the UK, these would cover 20,880,000 square feet overall. In square kilometres, that's 1.94 kilometres squared, a measly amount compared to the UK's 243,610km squared. This means that there is a 0.000000093% chance of being within sight of a pub if you place a random point anywhere in the UK, but every active graticule has more than one pub. I think this is closer to the mark because there is a lot of empty space in the UK. If you live in a city like London or Glasgow, the chance goes up significantly. If your graticule is in a town, It would still be high due to the one-pub-per-five-kilometres rule I said before, graticules being much bigger than that. If you live in a wooden shack in the middle of desolateness/nowhere, you have no chance. All the pubs in England do not make up for the empty fields of England, apparently. I just learnt how to use signatures! --The Man Himself (talk) 10:28, 1 March 2017 (UTC)
