So many years ago, I forgot this, but this thread has refreshed my memory... Dad stopped at that little liquor store just before crossing back into the great white north. He bought liquor and smokes AND he used a valve stem screw on the valve stem on the left rear tire, which he had inflated to twenty pounds over-pressure at the last service station south. He was, of course, wearing his dress RCAF, with commondations from several theatres, uniform.

The "boarder" gentleman began with niceties, but was quickly taken with determining what the hell that hissing noise was. When he determined that we were about to have a flat tire, he urged my father to get to a service station nearby, complete with directions. We departed post haste, along with all the tobacco and liquor "above and beyond".
