"This is probably impossible, but who cares?"
Modern-day F1 is rubbish, and I blame the circuits—"facilities," in the current parlance. What a miserable, emasculated assortment of go-kart tracks. How can bravery and heroism occur in such sterile environments?
Regular visitors at e-Tracks feel the same way. They even get their own page to submit designs for fantasy tracks, like New Brands Hatch and the awesome Puget Motor Speedway ("The pride of the facility is the daunting and massive 8-mile (approx), 18-turn Grand Prix circuit"). The whole exercise really takes me back to grade 9 (usually in French class).
The site also has a nice feature article on Westwood. It says you can still make out part of the back straight through the trees. I almost wish I never read that; I'm going to have to make a pilgrimage now.
