I found a prime example of stupidity of this kind this past spring at
Guadeloupe NP, in the Texas panhandle.  They have a pleasant tent
campground and a separate RV campground which is simply a flat, desolate
asphalt parking lot, no picnic tables, no nothing.  We were cooking dinner
in the tent campground when a ranger approached and demanded that we move
our "recreational vehicle" to the appropriate parking lot.  Now, next to us
was a man with an Chevy conversion van.  He had a small tent set up, but
clearly was camping and sleeping in his van.  That was OK with the
ranger,but in his mind the Westy was an RV and had to go park on the
asphalt with the Gulfstreams.  Henceforth I'll carry a small tent for this
kind of situation.
