bigbird,
I've never been to the Robinson show. I've seen it advertised several times but never went. I am from Newton. One to check out is the one in Effingham. I've been once and it was alright. Nothing special but it was still good.
Feb. 19-20, IL, 2011, Effingham. Gun, Knife, Hunting & Trade Show. Knights of Columbus, I-57 & 70 at Fayette St. SH: Sat. 9am-5pm, Sun. 9am-4pm. ECA Inc., PO Box 138, Centralia, IL, 62801. PH: 618-495-2572.
It is a pretty good show, not huge, but lots of stuff to look at. Prices might be better, not sure.
