Good news, Dan, and thank you for posting. There are not many gunshows in northern New England, where I live, and the "obama effect" was very much in play the last gunshow I attended; Concord, New Hampshire in March.
Line was 1 hour long at show's opening. When I left, the line had grown to an hour and a half. The dilemma, for me, is this: I like the fact that gun sales are off the charts as it is a metric to gauge opposition to the leader of the free world. The downside, (inavailability of ammo), gives closure to the dilemma.
