  • I (YellowYoshi) am expecting to be there as well, with one or two people :-) I must admit that I'm cheating, since I actually belong to the graticule to the east.
    • Heh, so do I. Living near the edge of a graticule has its bonuses, I guess . . . --Paradox7
  • I'll show up as well (Spider)
    • We wound up with a little crowd, it was fun. I'm just sad we'll be out of town this weekend and we'll miss the big meetup downtown. (moodygrrl)

Notable Hash Dates

• May 30, 2008 The geohash was located somewhere in fermilab!! I think that probably qualifies as the nerdiest geohash ever. Its a shame it was a work day, and Due to the script malfunction on that day, I (spider) didn't learn about it until the day after.

• June 20, 2008: According to the calculator, it looks like it's back at Fermilab, off in the northeast corner near the end of Power Line Road (it's hard to miss, that's the road that goes along the huge Pi-shaped power line supports). Unfortunately, it's not a public area, so you'd probably have to settle for Wilson Hall or the Buffalo Farm if you're not an employee here. (logic)
  • And I (virgletati) just happen to be a Fermilab employee.
