Harry,
It was at least 4 years ago. I went down thru the list of parks on the site you put in and I could not remember the name of where we stayed. We really lucked out. I understood they had 50 amp and plenty of it. The plastic coach owners I traveled with hardly knew anything about 50 amp. They were satisfied with 30.
I care not to go over the gorder again. There's too much to see in the good ol' USA
