For those that haven't done the Twisted Sisters yet, DO IT! I've only been 4 or 5 times now, but it's by far the best drive I've done since I left NJ/NY.
But make sure your brakes are on point if you're going to maintain the speed limit at all times. I had to gutter technique in the FRS once. Literally. Dude behind me thought I was a pro. I honestly thought I was lucky to be alive.
