Holy Ballz this is cool. I didn't hear about until Allison told me last night what it was. Turns out there are thousands of presents hidden all around you. Even in my butt-fuck-no-where neighborhood! I paid $10 to get an Iphone app called Geocaching and it was so worth it. Really neat! Try it out! There are free ones but I didnt try it. You can also go to
