I was checking this out and got confused because it's the same weekend as the World Series of Speed asphalt races at Thompson Speedway Motorsports Park also in Thompson, CT. I thought the HOCOC race might be being held at the full size car races. I'm not an HO scale racer but have been to the tracks in Ashland, MA (Modelville Hobbies) and was amazed by the setup and speed of the cars.
I'll keep your series in mind and may ask if I can be a spectator at a race sometime since CT and MA are not too far from me in Maine. I'll gladly pay the entry fee to support the event.
