No I wasn't referring to the beagle. I would expect that if there was one (never noticed any at LAX) & I had food the beagle would catch it as he did in ORD w/ the apple, and I'd be sidetracked to ag.
I thought this being picked came from the screen when I first entered the customs area from the plane (could be wrong; no idea what was actually on the screen in front of the customs guy), and when I got ready to exit after getting my luggage the guy looking at the stamp sidetracked me to the ag x-ray machine. It only took 30 seconds at the machine for my stuff to go through & then I was on my way.
Cheers.
