Sometime around noon I will depart to prowl the aisles at the Indy 1500.
The dynamics of gun shows are well on their way to coming full circle. Most started off as ways for collectors to meet and ogle each others collections, swap guns, and sell off excess pieces. Over time, new guns, accessories, ammunition, and all manner of other things shoehorned their way in. Desperate to fill table space, some show organizers even let people set up tables full of Beanie Babies or whatever, which triggered an inevitable backlash.
Two things changed this.
First, the virtual elimination of "kitchen table" FFLs in the 1990s meant that new guns at gun shows were no longer cheaper than they were at brick and mortar gun stores, because most of the sellers now were brick and mortar gun stores. Contrary to popular belief, transporting inventory to a show, renting tables, and paying staff overtime to man them means that selling them cheaper than you would back at the store is not really a winning business plan. And if it's just a common used gun you're looking for, there are probably a hundred for sale on GunBroker.
Which brings us to the second big change: the internet. I used to go to gun shows looking for ammo and accessories and parts and books, but nowadays you can get almost all that stuff off the internet any time you want to, and frequently cheaper.
Pretty soon, the only good reason to go to a gun show will be to buy some beef jerky and browse up and down aisles of antique Mausers and old Smith & Wessons. Which is kinda why I go in the first place, actually. I sure won't miss the Beanie Babies...
