It was with REI, and we were on the Potomac at Riley's Lock.
We reviewed a few strokes, then did self rescue using a paddle float, and also helped someone else by turning over and emptying their boat, then stabilizing it while they got back in. The latter I could do, with a bit of struggle.
But oh my, the self rescue ate my lunch. I was doing something wrong, and couldn't get the paddle (with float) to stay perpendicular to the boat, so I kept falling back in. My boat has a big cockpit so there's not much room at the front of the boat, but I think the problem was with me and not related to the boat I've got. I told Kalidurga and 7rider that I can never go kayaking alone, because there's no way I could save myself. I am extremely sore today.
The water was in the high 60s and there was a lot of "salad" in the water. It wasn't bad unless you had to stay in the water forever as you tried over and over to get back in. By the end I was a bit chilly. The rain held off till we were done, so that was good.
All in all, a frustrating day.
