OK, I've been running on the Big Willow circuit in P&G for a few days.
First off, this is a nice improvement on the previous versions of Willow that I've used for a few years now. Nicer details, better skies, the surrounding landscape looks right, and of course the pits are now on the correct side of the main straight.
The only thing I've noticed up to this point is that the start lights and/or flag man are really hard to find, particularly if you qualify on pole (don't we all?). Overall I'm really pleased with this. Thanks Gwaldock!
One kinda silly detail that would be fun is to put the "House of Charmin" signage up on the main restrooms. Hey, I notice these things. Here's a pic, circa 1967 of my Sunbeam Alpine at Willow.
