Freshwater Jaws. 😄
What's funny is after that happened I only jumped in the water to pee and cool off for less than a minute and hung on to the ladder.
We were at Lake Mead over the Labor Day weekend and I noticed this rolling about a 1\2 mile out. It was moving across the middle of the lake towards us. It was not a wake from another boat because there was no boats around and no boats had past in a while. Also a boat wake would slowly dissipate...
I'm not far from @dbart and last week at night there was one running down the street and I don't live by any parks or golf courses. It was pretty crazy.
