I don't know what it means but I have seen more activity from the Border Patrol on this trip though the southwest than in all my previous trips. Perhaps the additions to the personell since 9/11 is finally paying off. Or maybe Washington is actually listening...nah, that can't be right.
At any rate we have seen more patrol vehicles out than I have ever seen, plus twice I've seen Patrol Officers on overpasses watching the trains move under, looking for the wetbacks hiding on the freight cars.
I also saw a couple of BP Stations with their flags at half mast, though I have heard nothing about why.
