On a field near Zimmernsupra, Thuringia, Germany.
We couldn't quite decide if we'd make it two single hashes after work or a midnight double. So instead we went for a no-midnight-double, i.e. trying to get both in a night but explicitely not hitting midnight as we couldn't be asked to get the timing just right (and we both have done our share of midnights ;).
Straight forward. Rincewind came by Mampfred's place at 11:15pm and we headed out. Got there around 11:50, shot a stupid grin and went on to 2012-10-25 50 10 ...
See here combined for both hashes.
