I got my dragon from TC Reptiles and yes they are still breeding their own. I think they only have a few clutches a year though because I haven't seen any new ones since I got mine in October (they had clutches hatch on 9/5 and 9/10)
I havent made it over to Leapin Lizards but besides those 2 I'm not sure if there are really any others outside the chain stores. Most of the breeders on this site aren't in the midwest area either unfortunately
I missed the March expo but I will definitely be at the August one.
