i got rousted once in oregon in my motorhome.
spent an hour trying to make the cops understand that i was parked,
so i could hve a snack and enjoy my show on tv.
they totally ran my a55 thru the ringer, trying to charge me with attempting to camp!!
they finally went away, and after awhile i drove on.
unless you actually fall asleep while you are parked there, youre just enjoying the park!
