Hello,
I am nogons and I found out about geohashing when I was trying to read every xkcd comic. Now I really want to try to get a bunch of achievements and shtuff. My friends and I have used "randonautica" in the past to find a random places. Its been some my favorite moments going to a random park or other area and finding cool things.
Unfortunately most of the area in my home graticule is water, but I'll try to go to all the ones available.
