License plates.

We've seen all 50 US plates on the trip. We started over in Yellowstone and have seen all 50 again over the last 3 days. There are also a surprising number of foreign plates besides the obvious (and numerous) Canadian ones. We've seen Australian and New Zealand plated RV's in multiple parks that must have boated over from home. There have been a couple of Europeans as well. We have also been on the other side of this with our rare New Hampshire plate. I have twice been asked for permission (by non-Americans) to take pictures of our plate for their collection.
