I have never found an accurate and up-to-date listing online. The Shotgun News list is the best online, but usually incomplete. Sorry, bottom line is if you want good info, you are going to have to pay for it.
The best source I have found is "Gun-Knife Show Calendar", a magazine published four times a year by Gun List. It has listings by date, cross indexed by state. It costs $3.98. I buy it at Barnes & Noble. Subscription is $15 a year, at 800-258-0929.
The current issue covers Oct/Nov/Dec 2000. It has listings out to Feb, 2001, but you will find the listings that far out to be incomplete as we get into the new year.
SodaPop: I see listing for shows Nov 11-12 in Allentown, New Kensington, York, and Pottstown. Nov. 18-19 in Reading, Canonsburg, and Erie. Hope this helps.
