Lost a good friend to a boating accident..years ago at Lake Havasu.
It was during spring break & the river/lake was packed with people..so many boats that you could literally jump from one to another.
I never went back.
I'd guess only tourists and the college crowd would ignorant enough to do that. That's really the last place you want to be during that time. I personally wouldn't go there at that time even with all expenses paid.
