I've been caught a few times, once on Mashpee-Wakebye pond in a bass tournament and another off Cohasset; both fast movers giving you no time to beat feet. I remember making a long cast during that bass tourney and watching in disbelief as my line suddenly arched up probably 15 feet above parallel and right after there was a massive crack of thunder. I was close to an island in the back with a large oak tree I could tuck my bow under to be lower.
That cohasset storm was unreal, we were drifting eels and catching some nice 20-30lbers on ever drift and the conditions were pretty flat and in minutes it was raining sideways and waves built to nasty in no time. We tucked in behind a ledge to wait it out and of course after the tide and the bite had died.
Don't like to be out golfing in it either
