What a total pain in the A@@. Stopped to get gas before we crossed. No cars waiting. By the time we were done there were about 10 cars. Waiting . . . waiting . . . . waiting . . . . waiting . . . . . and yeah, more WAITING! People started beeping their horns. There was nobody in the booth on the US side and I guess the first car in the front didn't want to blow through the stop sign (I would have). Finally, 3 CBP agents come strolling over - they were on break and had gone to the store!!!!!!! So they leave the grand ol' US of A completely unguarded to go on break???????? Every time it seems like it gets harder and harder to get OUT of the country!
