I'd certainly welcome an event like this. California! Colorado! The West! (not Florida! Flat, bugs, uninteresting in my opinion - unless what you
really want to do is go fishing and play Golf every day)
California has some great roads, excellent weather most of the year. Places to see!
We've got Mountains (Big, beautiful Mountains, and smaller rolling green hills in "The Gold Country")
Deserts! Care to test your English cooling system in Death Valley? (It's actually quite beautiful in the Spring!
The Pacific coastline is spectacular.
Lakes! - Lake Tahoe! (gorgeous, AND there are Casinos)
Palm trees, Redwoods, vineyards (Sonoma valley, Alexander valley, Napa),
Excellent food, depending on where you go.
The Grand Canyon, Yellowstone, Sedona. Gold Country. The "lost Coast Highway". And, yes, racetracks.
Take your pick!
Go fast? Tour? There's so much to choose from!
I've done the Amici Americani delle Mille Miglia (the California Mille Miglia) several times (rest in Peace, Martin Swig). 1000 miles in 4 days - easy and fun. Something like that could be arranged. (Our Fruas are too new for the Mille - 1956 or older)
But come on over for the Copperstate 1000. Requirement is for cars of 1973 or older. I don't think there's ever been a single 428 entered - and the 428 is PERFECT for this event. The rarity of 428's improves the chance of being accepted.

There are quite a few Brits who ship their cars for these events. Not to be missed! (easy for me to say - I live here).
