I'm going to use Mapquest, but I'm headed to Patty soon and I'm wondering which route is best. Heard I could take the Nogales exit, but that I-10 East to Sonoita might be better. Any details that would help would be appreciated. Never been there.
I19 is an easier tow. East siders usually go through Sonoita, West side usually run I19. I would recommend the Sonoita highway, at least once, if you're traveling during the day. It's really nice this time of year, the mountains and high desert grass are really green.
