if you like Geocaching, check out the Degree Confluence Project...

Similar to Geocaching in the fact that you are hunting for certain coordinates, but the objective isn't to find a hidden treasure... it's to visit all of the exact whole number intersections of Lattitude and Longitude coordinates. Usually you take a picture of your GPS screen and of the view to prove you where there and share what it looks like. Sometimes this might just be out in a field, other times it might be in the ocean or on the side of a cliff wall, or even in the middle of someones house!

 

I believe all the US ones have been visited multiple times, but it's still a fun challenge if you have a GPS and are looking for an adventure.
