Second para about liquor: I was passing through Buffalo, noticed impounded American twin Cessna 310. Asked US Customs what that was all about; they said the owner had an undeclared magnum bottle of rum from St. Pierre et Miquelon, the French islands about 120nm north of here. Highly doubtful, you say? Carrying firearms across the border of any kind by any means without permission is prohibited. However, firearms are permissible where aircraft are operating in areas and at times of the year when survivability may be jeopardized without them. I'm in those spaces much of the time.
