Hi Matt,
Glad to hear you're in one piece, your drive back from Road Atlanta must have seemed like a long'un, if only from the perspective of 'WTF's waiting for me when I get there?'. Similarly, a walk to the dentist at the top of our street can take me several days. I once got jet lag visiting the STD clinic in Sunderland.
I don't think I've had any real monster drives though, let's face it, you lads are in the best place for that. Surrey to the Isle of Skye was a biggie, about 14 or 15 hours door to door, non-stop apart from the ferry, I got a little dismayed when I realised Glasgow was about half way. Almost got my my little (at the time) sidekick to puke badly when enjoying some of the Great Wee Roads on the West Coast. Going there was fine, once over the border the driving just got better and better. The return leg was suicide inducing though, there's nothing like the prospect of the M25 towards the end of your journey to dampen ones spirits. The fuel bill was also entertaining, I had to fill up five times in that 14 hours. Don't mention my haemorrhoids. I had to treat them later with some Leather Nourisher.
A high speed blast to Milan in a 500 Merc to catch some of the 1990 World Cup, was also quite a wheeze. (literally, have you ever kicked a ball about in a service station up a mountain in Switzerland!) but we rotated the driving on that one. Nice car though, we set the cruise at 140 and just watched the miles fall away.
Aaah, salad days...
