I was in the Wet n Wild waterpark in Vegas about 10 years ago and found a little less then a 1/4 floating through the lazy river thing that flowed around the park. I was actually looking for money at the time, because I had found 30-40 bucks floating through the thing throughout the day. I grabbed the bag thinkin it was money....unfortunatly it wasnt a ziplock and was totally trashed, but thats the only time I ever found any. Unless you count the time I found my dad and stepmoms stash hehe. But thats another story
