BC Provincial Parks

You'll find attendants collecting at almost all PP's and they should be open now. Alaska is where you're likely to run into more Iron Rangers. PP's don't take checks from Americans, at least not in my experience, but they will take US cash most of the time at some approximation of the exchange rate. One other thing as far as route, it's way quicker to take #5 to Kamloops than to go up #1/97 to Cache Creek. #1 is mostly 2 lanes with some passing lanes, but #5 4 lane all the way to Kamloops and very lightly traveled. More scenic too!
