Northern Cascades?

Hello all
i am looking for info from northern cascades climbers...I was planning on going to the Tetons again this summer for 20 days (august 22-sept 13 ish) but i decided that i would like to try someplace new and i was thinking the cascades, however i cannot afford a rental car and plan on hitching around once i fly in (should i fly into bellingham?)
are there any major campsite areas (like the climbers ranch in the Tetons, Camp 4 in the valley, or Miguels at the red) that are good places to find partners, sleep, and get food? i want to climb every day, and do not mind soloing stuff if no one is available, but im pretty much down to get on any route.

thoughts?

check out cascadeclimbers.com I am sure you can find someone who is up for an adventure. I am not sure if there are any places like Camp 4 or the climbers ranch, but I am sure their forum would have some great info for you.
