Sweet, good to see another active geohasher here! If you post to the Seattle page (or its talk page) before you go, then others can find out... and likewise if you put the seattle page on your "watchlist" (and set your preferences so that you get emailed when someone changes one of your "watchlist" pages) then you'll know when other people are going for one. (That's how I just found you!)
Best of luck!

Also, looks like you've got your golf hash tomorrow if you want it. I don't know how to golf unfortunately. OtherJack 13:48, 13 April 2012 (EDT)
Beware the lack of documenting an expedition for the Ides of March! Looking forward to hearing about your success soon. --Thomcat 13:56, 22 August 2012 (EDT)
