I just returned from a gun show in Grand Forks. Interesting experience.
First, a reminder - I'm in North Dakota, so your experiences may vary.
Lots of tables, maybe 30 double rows (long, O-shaped setups) of tables at the Alerus Center in GF - sports, conventions and shows like this. Each O was maybe 50 (6 tables lengthwise) feet long and 12-15 feet wide (2 tables).
Packed, lots of people, and I was there 45 minutes after they opened. Quite a few EBRs, ranging in price from 900 for a nice Bushmaster or DPMS, to 1500 for the same thing at another table. A surprising number of Colt and Armalite ARs too, including some in original looking configurations, one was stated as being from 1977, another from 1968. A number of AKs as well, including a bullpup variant as well as a number with folding stocks. SKS' too, nice selection. One Johnson from 1943 for "only" $3500.
Tons of bolt-actions - that no one was looking at. Shotguns got a bit of interest, but most were on the tables.
A lot of gear as well - gun cases, bags, etc. lots of digital camo too.
Almost no ammo, except in odd calibers. I did manage to score some Wolf military AK ammo for $5.75 a box - far better than the local cheapest store wanting $12 for Golden Bear. Very very little reloading stuff other than lots of dies. I think I saw one retailer selling brass. Bullets? fuggetaboutit.
And I managed to find a nice used Sig clip magazine for only $30. I bought that from a guy advertising himself - Haz, this is for you! - "Clips 'B' Us" - I am not joking. In fact, everyone selling clips - er - magazines were calling them just that - clips. Did I mention that most of the attendees appeared to be FUDDS.
Oh, yeah, the ATF had a booth there as well. I had never seen that before. Apparently they were invited to set up, interesting idea.
Back to you, Chet . . .
