Windbreaker

It has been some years ago but at that time it was enforced. The problem is that longer trailers present a danger to themselves and other traffic on the way up and down.

Things may have changed, I don't know. However there was, up to about 5 months ago camps for RVs by the river. It is my guess that they are still there. But be forwarned, camping in that park is under review ATT and may well be lost because of the low air quality in the park. (caused mostly by electric plants in Mexico, how camping impacts air quality was not made clear)
