I would have called a friend and asked them to bring a case, duffle bag, etc. to me before the border and drop off the cases, then the friend could have gone through and immediately returned and stopped on the other side of the road, whatever, and he could have transferred the stuff
Respectfully, logistically impossible. The road is like a freeway - one way, with barriers on each shoulder. No where to pull over, and if he just stopped, the traffic jam would have made it darn near impossible for a friend to ride to the rescue. The return trip, for the friend, would not have been immediate, it takes several hours to cross back into the U.S., at that crossing, and then the north bound lanes are a significant distance from the southbound lanes - no real chance to just hop into the next lanes, pick up the weapons, and return to a waiting vehicle. Add to that, he was in the process of moving from Florida to San Diego, how many friend’s did he have, in the area, to call ? I opined in an earlier comment, in retrospect, it would have been better to just shut down, right there, and let the Calif. Highway Patrol tow his vehicle to a storage yard. Thank you.
Frankly, had it been as you described, I would have just had a “breakdown” and took my chances on this side of the border. You can’t tell me that breakdowns haven’t happened there before. That is IF I were legally carrying the weapons to start with. It is better to create a legal disturbance than in illegal one.
