IMHO the 2 best shows in Alabama are the Collector Show in Hoover ( B'ham ) & the Huntsville show . I missed the Shriner show this past weekend in Mobile due to weather Sat & got up too late on Sunday . Probably hit the P'cola show this coming weekend just to see what's available .
The ALGCA spring show is the weekend of March 21st this year. I went to it back when it was still in the Birmingham Convention Center and it was huge. I plan on making the pilgrimage. Go early enough and you would have time to visit the CMP in Anniston before they close for the day.
