Mojo, if you want to enter at Mexicali, use the old Calexico port, take the road to San Felipe just as you get outside of Mexicali you will come to a freeway, take the one that says carretera Mexicali a San Luis, once you arive in San Luis (about 40 minutes) you will be on the street called Obregon in town, also it is highway 2,as pinto point says go right on hiway 3. Its about 2 !/2 hours from there to RP. If you want to come back that way but want to avoid long lines at the border, once you get back to San Luis, stay on Obregon just like you came, cross back into Baja and take the road to Algodones. When you cross here you will be back in California and usually no wait at all. The port at Algodones closes at 8 oclock. From Mexicali you will pay 3 tolls 16 pesos from Mexicali to San Luis, then when you arrive in San luis another 16 pesos and when you get to the toll booth for hiway 3 you will pay 94 pesos. Time wise from Mexicali to RP is about 3 hours and 15 minutes but sometimes there are long lines coming into Mexicali from Calexico. As Pinto Point also mentioned Lukeville is easier but maybe not faster or prettier. If you decide to go the Gila Bend way it is about 300 miles from Calexico (Mexicali) to RP, if you go the Mexicali way I think its only about 180 miles to RP plus a few miles of in town driving in Mexicali.
