The thing that got me about the section of the Lowers I paddled was how much awesome surfing there was. there were waves all the way across the river in all different places. You could have 100 boaters playing in all the spots with such a wide river. It would take Eckilson about 5 hours just to run the first mile and a half with all the surf waves.
IMO, the Lowers is something we should get used to paddling, because there isn't anything else like it in MA or CT that I've seen.
