40 / m / 26,-80
I live in the Palm Beach graticule (in Pompano Beach) but i'm willing to go to Miami or St. Lucie on a saturday, or if there's something really worth the drive.
I have no GPS, but I have google maps on the phone and can get to the graticule by comparing its point on a map to nearby roads or approximate distances.
(Still looking for the best GPS cellphone for geohashing that isn't an iPhone)
