So, I took my Stock Wrangler out to Reddington Pass, here in Tucson, a few months ago, it was great. But, I messed up my rear bumper a bit. And I'm wondering if it's legal to drive without a rear bumper here in AZ. I'm currently driving around with it on, but, I'd like to take it off because aesthetically, it's ugly. I know I've seen Wranglers around town without them, but, I want to be sure before I take mine off.
