I fun floated the current two days ago with my girlfriend's family.
We were in tubes, and a couple times we had jets cutting between us and the bank (small, small spaces) multiple times, Weaving in and out of tubes, stupid.
My thing was, it was the same guys ALL DAY LONG. They were literally just running the river to piss us floaters off. Some guys we saw go by 6 or 7 times, looking like they were running an obstacle course between tubes and canoes.
For those that jet boat, cool, but it was those we were seeing that give jet boaters a bad name, and the reason so many people don't like them. They weren't fishing, they weren't pulled up on a gravel bar hanging out. They just wanted to run a 5 mile stretch of river to make people mad. I was amazed we didn't see anyone get hit that day, and it wasn't even that busy on the river.
