My cousin and I are considering taking spring break (exact middle week of March) and somewhat re-tracing the Oregon Trail, because we are awesome people. We love to camp, but are both summer campers. I'm curious if anyone has had experience tent-camping in the southern Wyoming and into Idaho region? We may jump up to the Tetons too as we've both never been there. Just wanting to be prepared for the temperatures - will campgrounds even be open? It will be much cheaper to go the camping route, if we think we will survive it!
