but, I suppose depending on your definition of wilderness, I'm not sure wilderness trips involving a lot of portaging is a good idea by kayak. That's really not their forte, but not all "wilderness" involves portages.
I see you're from Calif. I bet there's a lot of paddling in the Baja, for instance, that most of us would consider wilderness. My friend Tom has done an awful lot along the northern shores of the Great Lakes that covers some pretty wild country. The New England, Nova Scotia, Labrador, coast would certainly qualify and not necessarily require many, if any portages. The list is endless. Some of the Western Rivers cover some pretty wild country and not all involve big whitewater.
Same with the far south... the bayou country can be pretty darned wild.
We can debate the meaning of "wilderness" endlessly and ultimately everyone will probably arrive at their own definitions, but portaging surely isn't a prime requirement. Its the off season. (Well, for many of us non-Californians anyhow.) Time to break out the maps and start dreaming and planning. Some wilderness requires permits. Not too soon to think about applying for those...
