Hey there is a good one going in between liberty and smithville, it is right off 291, I think it is Sherman road or something like that, it is the last exit until you get to 435 as you are heading out of liberty, it is about 8-10 miles and it is only a 45 speed limit, but with my last car I usually ran about 95-100 on the straights and there was some very tight and challenging curves, lots of different speeds, be careful if you have never driven it though, when you are coming from smithville to liberty there is one curve that comes up and the whole back end of the car gets light, well I totalled my first Si on that road as it was my first time driving it, it was 4:30 am, it was raining, and my tires on that car sucked ass, plus I was going about 10 mph too fast, so I ended up totalling my car.
