Rob: Yes Kino is in the no hassle zone . But that does not apply to RV's. You still need a 10 year permit. That is a hassle. It is so darn confusing! PP is a free zone so NO permits are required. There have been some Mexican Americans who had their vehicles seized by heading East towards Cananea with no permits. I actually went out @ Douglas in my PU a few years ago but luckily was never stopped.
