General New England area.
They Key is following Certain group leaders on Facebook but not following the group themselves. Reading comments and post from most groups is a great way to get brain cancer as fanboyism is rampant. If you just send a friend request to the guys that organize the events you can just show up and skip all the drama. Those are good for drag events, shows and cruises. For actual track time visit
Lime Rock Park - Lime Rock Park and join one of the groups. Its not cheap but you will be able to run the car around the track on whatever days your group has the track. Palmer Motorsports should open this summer and I feel that this will be fantastic since it will be a true race weekend type of track.
Kancamugus.... this one is tricky since you have to chase motorcycle groups since I found car clubs are very docile with these(at least the ones i found). So these I tag along the bike groups with a few cars and tons of bikes. What these guys do in these runs... isn't exactly...shall we say "legal" however a well balanced solstice will not get left behind as it will turn faster than most guys can ride their bikes. Most wont mind as long as you don't get in their way. Alot of guys feel they have the right of way even when passing on the right or wrong side of the road. Best to join this if you have group riding experience and know how deal with people with more horsepower than brains. Most are nice guys but some have a death wish. The crazier guys generally wait for the group to catch up when they get their fix.
Or find 5 to 10 friends and go up there for the weekend on your own.
If a summer full if fun its the goal then its a juggling act of being able to sneak into the best runs. At least for me since I don't have the patience of being a club member.
