Letter Boxing

So my sister told us about Letter Boxing. Brett had heard of it before but called a different name. Well we decided to go find one today. For those of you who don't know what it is, people hide a box in random places and then give you clues as to where to find it. It took a little bit cause it said it was hidden in a flag heart shaped box. But when we found it it was in a film case. Anyways, whats funny is it was in a place that we always pass when ever we go to this park and never knew it was there.
