My fist cache was a micro, so on my second which was a ammo can in an important area to me with a nice little hike, I went a little bigger than normal.
I had bought a copy of "The Simpsons DVD season 10" at a Circuit City going out of business sale. Only to get home and realize I already had it. It had cost me $20, and I couldn't return it, so into the cache it went as a FTF prize.
