No, in fact I've been happily surprised how many larger (including
airline and military co-use) airports still allow me to drive my
rental car up to the plane. They probably understand that we are not a

Agreed. Best of all, common sense seems to have reared its ugly head
again, nationwide, since 9/11.

Right after the terrortist attacks on New York and Washington, nearly
everyone restricted drive-on traffic at airports. Now, on our recent
trip across the country (WV, NC, SC, AL, TN, MS), we were once again
able to pick up our rental cars right at our airplane at every airport
we visited.


Here in Montana we didn't change one iota. If you could drive on the
airport before you still can. No new fences, no new locks, no new rules.
