Hi folks, I'm from Brazil, and I will be attending the Nats this year again. My first leg will be Chicago->Idianapolis->Lexington->Dayton by car. Then Dayton to Fort Wayne. I would appreciate if you guys know about hobby shops - plastic or railroad along this route. I don't mind to deviate a few miles to visit a nice shop. Any help, please. Thanks in advance.
