Meet Tony and his dog, Sadie. Tony was working on this raft for quite a while, planning to take it out on the ocean, with a tent on it, for an extended cruise. He took it for a test float on the river and someone called the police, who made him take it home and told him not to try it on the ocean, or he would be arrested. Sad to say, he abandoned his (sea) worthy quest.
This is a pretty remarkable feat of nautical engineering, as you can see. Note the water skis.
