For what it's worth, the following cookoffs are scheduled for the same weekend:
KCBS - Shawnee, OK 371 miles away and will draw most of the OK crowd
IBCA - Ennis, TX 137 miles and just south of Dallas
Wills Point, TX 172 miles and just east of Dallas
Bossier City, LA 191 miles
Corpus Christi, TX 276 miles and will draw from Houston and south
Geronimo, TX 185 miles and will draw from Houston and west
Did not see any Lone Star or Texas Gulf Coast scheduled for that weekend yet.
There's a potential for the Sam's Club events to conflict as well.
