We're not a neat freaks, but.......

It always amazes me the parks that won't let you wash your rig, especially those that offer monthly/seasonal rates.
As a former boater, black streaks drive us crazy.  So, after a particularly rainy week last week, we had a ton of black streaks.  Fortunately, the park we're staying (Cardinal Camping Center) doesn't have anything in the rules about washing your rig.  It's the old saying "better to ask forgiveness than permission" time.
We know there's extra expense in people washing their RV's, but honestly, wouldn't it look better upon your park to have shiny RV's in there than black streaky, nasty ones?
