Call Tom at Bruckner Hobbies in the Bronx, NY - I believe he's running an on-road series at a brand-new track in Bridgeport, CT. I've seen videos of it and it looks like the West Coast tracks - really professional!
Jamie runs some nice races in Middletown, NY.
Also call Nitro Mike or Rob at Brooklyn Hobbies - they may be doing something at Floyd Bennett Field this year.
