will be in Phoenix for 4 days next week w/ my 13 yr old son for skateboarding championships.....we will be checking out as many skate parks as possible but wondered if a day trip to Mexico is far and/ or worthwhile? Not for skateboarding, just for the sights, um to see another country, I guess. Do we need a passport? Any skateboarders out there that want to recommend some awesome skate spots near Peoria? Thanks!!
