All I need is a lake house, a dock, some plastic barrels from the dump, and build a gym on my dock, my neighbors wont think its weird, not a bit.

(Actually a guy here in NH on 111 in Kingston sells those barrels out front of his house, if I see them all gone, I know the gym bro's are buying them up).
The guy lives near a lake in Kingston as well.
There was a weird guy on the webs years ago who used to lift with some machine in a lake, odd...
Looks like it may be a thing now, google "underwater weight lifting" and look at Images, bunch of weirdo's.
