Let’s hear about the infractions then we can make a more clear assessment. They gripe about my utility trailer you can’t see from the road. I’ve learned that sending multiple certified letters with 10 days to respond slows them down and aggravated them.

Also helps to mention in your letters other people violating the rules that you have seen and ask for copies of the letter they received.
