This route I posted on the NYC Rollcall is out east in Suffolk County, there is a 3 mile stretch of roads with about 20-30 turns, long sweeping turns, tight turns, turns that change elevation, and long straightaways. A little far to get out here but definitely an awesome ride. It is the closest you can get to a roller coaster without the long lines. I tried finding that road you had mentioned in Nassau but couldn't find it, do you have a link for that on google maps?
