I've pulled open wheeled trailers a lot and have never been hasseled by a police person.
The other day, in a small Idaho town, I stopped to do some business with a local. A cop pulled up beside me. He admired the tear and then said "You will want to get some fenders."
My question: How many don't run fenders, and have no immediate thoughts to change?
Said another way: How long can I get away without fenders?
I am in San Francisco now, having pulled my fenderless tear from Idaho. No one seemed to notice or care.
