of the now 5 paddling sites I visit I have received some of the most useful guidance from Quiet Journey. http://www.quietjourney.com/community/YABB.cgi I'd suggest that it's worth contributing and becoming an Inukshuk. The Memory Maps and PCD that seem to be centered at QJ are alone good enough.
I alos like the others noted: Solotripping and BWCA.COM. All valuable resources.
