That's a nice looking boat! I used to have a beautiful International 505 that had mahogany veneer over carbon tanks. I'd walk back to it in the parking lot and there'd be a crowd waiting to ask questions. Much like driving a Grenadier.
America, especially out West, is definitely different than the UK. In Idaho, our controlled-access roads are speed-limited to 80 mph. Two lane highways are outside of cities are 65, although everyone drives 75 on them. In the mountains, the speeds are 65 or sometimes slower for particularly congested areas. Idaho also has a law that if you have 2 or more vehicles behind you, you have to pull out at the turnouts we provide in the mountains. Lots of RVs (caravans) and trailers in the mountains gumming up the free flow of traffic.
But you need those higher speeds to get anywhere. I hopped over to pick this boat up at the Sweet Grass/Coutts border crossing with Canada next door in Montana. From Boise that was 700 miles each way. The guy I met there had just driven 3000 miles from Halifax with it.
I don't know how you all drive a real vehicle on some of those roads, though. I was just in Normandy driving a BMW and was at times wishing for something more manageable
