Checking Premier's page, the Mesquite (TX) show is going to US$12; but the Fort Worth show is still $10 (parking over by all the museums has gone from $10 to $12, though.
Dallas Arms & Knife will be returning to Southfork Ranch, out in Parker, and will be $10 still (probably not worth the 50 mile drive to me).
Texas Guns Shows will return to the Gaylord Resort in Grapevine, for $20 (which reflects how much they want for rent at the Gaylord).
The Frisco Gun Show will be in the Frisco Conference Center, and the rental cost is reflected in the admission--$20
Premiere is not having an Allen show until August, at the Event Center, and it's $12, up a couple of bucks.
So, not many hits from inflation or venue rent rate changes.
