Hobby shops in Dallas/Ft. Worth, Charlotte, Nashville

I'm headed to Dallas/Ft. Worth, Charlotte, and Nashville, TN soon. I always enjoy visiting the local hobby shops when I travel to see what they have. Tracking down LHS on the Internet can be really tough. Anyone know of some good ones, especially mom and pops, that carry WW II era armor models in these cities?

Right now, I'm building a Bronco Models kit I found at King's Hobbies in Austin. It's a German 10.5cm howitzer mounted on a captured French Hotchkiss H39 chassis. I didn't even know there was such a thing. It still says Hotchkiss on the front! The literature says there were 48 of them in the 21st Panzer Division. 

Thanks for any suggestions.
