Hiring Harleys for say a 3 or 4 day trip.
A lake where we can/rent a boat for the day/fish/swim
Anything to do with NASA / Space exploration (assume there'd be something in Houston?)
A beach house for a few days
Cowboy or Native American Indian towns/experiences,rodeos etc. (I hope I have used the correct terminology, my apologies if not, put it down to me being a dumb limey).
Any local Motor racing events
Anything else you know of that would interest a group of 50 year olds who still think they're in their teens !
