I know what you all mean.
When I was young (about 10 years ago)
I was below our dam in the city, little pool of water about 50 yards across in any circle, and the river runs out, there was a lady fishing on one of the sides, I being young, and wanting to cross part of the river (knee deep) to get to a dry little island about the size of a car just to screw around. This lady watched me walk all the way around to her side and after I took my shoes and socks of and rolled up my pants, she tried to tell me I wasnt going in the water
Umm hmm, why not... Well the vibrations will scare the fish
Right lady, there is a rushing water 50yards away and my vibrations are going to scare it away, I ended up picking up my shoes and socks and when she thought I was going to walk away, I turned to walk away and turned and ran into the water. Took two bounds and I was on the island.
Oh that lady cussed me. I just walked out the other side of the river and walked up town.
