I try to attend any gun show within an hours drive from home. I have purchased (only) one shotgun at all the shows I have attended. I like to look at the guns and I usually buy reloading supplies and ammo, if they are reasonably priced. There was a guy who usually had a good supply of powder and primers. Of course he hasn't been at any show for the last 18 months.
Mainly I just like to look.
