I traveled in the Yukon and BC last sping also in the fall the previous year I stopped whenever i was tired and never had a problem. But if I have a choice I will stay in one of the many provincial camp grounds, I agree with Sue T. they are a great option far better than most commercial campgrounds which are usually just dusty parking lots. Also stop fairly early to give yourself time and a chance to find a suitable site. The rest areas; read the signs carefully some actually had a time limits. A little common sense will go along way, don't set up a permanent camp site or build a fire in the lot as I saw one do last year. The RCMP,s and the parks people are great they have a job to do, use some of the common sence god gave you and you'll be fine.
