As far as Rving they have a socialist view and don't want larger RVs of Americans and Canadians on public sites.
The cost is now huge where we once stayed for free, even where we could hook up on the shore of Superior. Lot less people then.
A certain lobby thinks camping is just that with tents, composting toilets and so on.Wait until those people get to 65 or so.
They come to the USA to RV.
