There are Border Patrol check points on all 3 freeways going out of San Diego County, but they are all within 100 miles of the Border.

Really? I have driven north out of San Diego on I-15 numerous times and have never seen a border patrol check point. Maybe I wasn't paying attention.

Actually four...Highway 94, plus Interstates 8, 15, and 5.
The ones on 15 and 5 are to the north and operate sporadically, probably based on intel and/or random checks.
