Greg, a really good video!
You pick up little things by watching vids. Some time ago, I noted that many people spread their legs out, drop their boots in the water. On a warm day, it really cools the feet down.
I hadn't done much of this with a pedal kayak but lately, when I am set up to fish in one location for awhile, I kick the legs out wide, akimbo, and it really feels good.
I see you do it, too!
