Steve,
Here is the link to the SOS event hosted by the Ohio Valley Military Society.
http://www.sosovms.com/show_of_shows.htm
Their event runs Thursday, Friday, Sat. and partial Sun. Yuu need to be a member to attend on Thursday (1st day with all the good luger deals). You can buy a membership at the door on Thurs. The public is welcomed on Fri and Sat only.
The National Gun Day event runs next door in the same convention center on Sat/Sun. (many guns sold at SOS on Thursday) end up being resold at higher $$'s at tghe NGD event...
