The Colorado River has a limited number of bridges crossing it on the CA/AZ border (about 10, maybe). It would be easy to put CHP armed with submachine guns on each crossing.[/quote]They can’t cover every location. I also presume he would not tell them that he is going that way before he does. He didn’t tell them that he was heading south on I5 to San Diego. There is a part of I5 that has no turnoffs. He took I15 north.. and there are parts of I15 that have no turnoffs for several miles. To get to Arizona, you can also go through Nevada then to Arizona..
