I heard about Chesapeake Paddlers Association back when I was taking lessons with Potomac Paddlesports. If I remember correctly, they have a pretty good paddling forum.

I need to get out in my kayak at least one more time before the season's over. My gear's getting dusty, shame on me I've thought of hauling the bike and the 'yak up to Big Pool at Ft Fred state park for a multi-sport day but have never gotten around to it. Don't think I could handle a 30+ mile ride and paddling on the same day, though.
