I love how a freaking trailer park can get so uppity.
Go ahead, try to enforce all the rules you want, there's still going to be a 50% concentration of scumbags with stained wifebeaters, 40oz malt liquors in hand and wild speedy eyes.
And they don't own reliable cars.
So there will be bicycles and motorcycles.
As for solicitors, nobody in their right mind would try to sell magazine subscriptions in a trailer park.
Vacuum cleaners or encyclopedias--No.
