I have some ideas for alternatives, but really, I can't offer up concrete suggestions until the snow melts...I just don't think the Gorge is a great idea. Too many car clouters. I'm sure GaryR has some good ideas too...especially out around Estacada.
“Twenty years from now you will be more disappointed by the things you didn’t do than by the ones you did do. So throw off the bowlines, sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.” – Mark Twain
