Here is the Silverado page on it http://silveradogunshow.com/schedule.html. I have been twice and got something each time, not a bad small show. One of the times they had some pieces up from the NRA museum, which was cool. I think I saw that the Mason Dixon Auto Auction gun show is this weekend as well, so you can go a little bit up 81 and get two in the same day.
Decent show this time prices coming back down on stuff md residents can't buy though,talked to the owner of precision firearms that builds the Ar15s at the show, I knew him back when he was in auto repair and guns was a side buisiness,that they will be leaving southern md and moving into the warhouse where this gun show is,more taxes lost to this state.
It was a nice small show, not crowded, decent prices.
At one table a guy had about 25 Yugo M57's. He was selling them for $190.00 with a box of ammo...I had to buy one.
