Mark your calendars for August 5,6, and 7. Put on by the Cumberland Motor Club in Maine. Friday is a test and tune and a ton of seat time running a short timed course as well as practice elements sim to the weekend autocross. Speeds are a bit higher as the facility is huge, tons of tarmac to play on. This club allows you to register yourself in 2 cars, your official timed run car, and any other car. Got a good friend wanting to go too? You both register yourselves in each car. Those who did got 16 runs on Saturday and 12 on Sunday. Lot of seat time for the buck as this event is a long drive away.
Last year I got told to drive from the Test and Tune to the pit area at no more than 50 mph. Well, buck 20 was a hoot but as more cars show up maybe 50 is a bit safer. You can camp on site, hotels too. Beer and food close by too.
