Recently I sent away for some tourist info on the state of Arkansas thinking this summer of traveling there for some camping and kayaking. Anyway, in the tour guide book (2008) there is a whole page (#32) devoted to geocaching and also the state, in honor of the 75th anniversary of their state park system, is going to release 5000 geocoins.
Also, in the back of the book they have the gps coordinates for landmarks, state parks, hotels, etc.
I know I sound like I'm one of Arkansas' publicity schmucks (I'm not----still living in the Michigan tundra) but I thought putting out this info was very cool.
Here's the link----
