My folks always liked to camp at the city park in Dumas, TX. I don't know how far that is from where you are, Charlie, and it's been about 5 years since they were able to do it. But, there's electrical
hookup (which in the TX panhandle in July is an absolute).
It's not in my old Trailer Life cg directory. I'll see if I can google some info on it.
Of course, there is also Palo Duro Canyon SP.
