Wretched circuit.
Every time a race comes up on this on Forza 4, I groan a little. Horrid hairpin at the bottom, nasty off-camber esses through the first section, fiddly artificially annoying bit at the top, too easy to take the escape road on the downhill section.
Only Laguna Seca is worse; a circuit famous for one awful chicane (the corkscrew) and being a bit dusty. Even the noisy runway section of Sebring isn't that bad.
BTW, Forza 4 is great fun.
