Wash Road (C757)
Located out towards Boston, Wash Road is an aggressively tight, single-track oddity in a region known for long straights. It requires continuous steering input and careful placement to keep the car settled over an intense sequence of sharp corners. The sheer density of the bends demands absolute concentration and leaves almost no room for error.
There are practically no passing places on the tightest sections, so you must scan ahead for oncoming farm traffic before committing to a sequence.
