Stowaway!!!!

Well, what do you know?  We have a stowaway!!!  We were eating our lunch on the boat when we heard a whimpering sound. We were inside the boat at the time. The sound seemed to be coming from outside on the back deck. I came out and listened for a while but didn't hear anything. I went back inside and we heard it again. This time I went out and looked a bit more closer and what did I see?  Trooper Dog!  He had his head stuck in the handle hole of the propane tank!!  That's why he was whimpering!  He has been hiding there, hoping we wouldn't discover him.
