Bill,
The NRA sponsors cash awards at a collectors show every year and they travel it around the country. This year it was in Dallas in Nov and then for 2019 they are going to the Sioux Falls, SD show in the middle of Feb. It's sure to be cold at that one, I have never been to the SF show but have heard lots of good things about it, the flyer says 1100 tables. This may be the closest in dates that they have held the show, it's usually closer to a year apart. This is the 24th annual NRA show.
