Pirates Booty Traditional Cache

I used to run around this lake a lot, but haven't much in the last few years since I live downtown now.  Was out grabbing some caches with a friend, and we wanted to place a more challenging one, which lead us to this idea.  

You may have to get your hands a little wet for this one, so doing it on a warm day is your best bet. Not a lot of room for goodies, since the contents of the container make this cache possible.  Enjoy!  

After finding the cache (spoiler alert): Please make sure the lid is sealed, and don't throw it back too hard, in order to not snap the fishing line.  Enjoy!
