My last visit to this show was in 2016.
The problem I have is these shows are scheduled right before a holiday weekend most of the time, or too early (March) or late (late November).
This schedule makes it nearly impossible for me to make it due to work and family stuff.
I've said for years - have one show, May thru September time frame. Perfect, no weather issues, etc. Then make sure the date does not conflict with other larger shows like Austin, Birmingham, and Orlando.
As for what I've heard, there are few "bargains" to be had. Last report from a friend who attended a few years back - collector prices that were too high or fixed.
I'd like to travel to Austin and Birmingham again, but flight prices plus lodging costs put this out of reeach nowadays. You need at least 3 grand to spend on records to make these shows worthwhile.
