As one of those who does stay at these big box store parking lots, I'll say some times it is the only alternative at the time.  Its easy for these two to say use an R/V park.  Except it is not as may time all are full.  At 11PM on a given night how many RV parks am I suppose to go check out to find an available spot.  All the parks I know of close there offices by 8 PM so you can not call and find space availability.  Again we have a solution in search of a problem.

Over the years I have spent many a nigh in isolated RV parks that had no sewer connection, no water hook up, maybe electrical connection.  These are called DRY CAMPGROUNDS and rely on the simple ability to have a place to park for the night rather than being on the street or highway.  Perhaps it time for these two assembly persons to actually research what the are talking about.  

I'm sure the person in a $ 100,000 RV is a major problem for Anchorage while the downtown area host street people sleeping in business doorway.
