Hey there, Rocking-M - This seems like a pretty neat idea and it sounds like you could have a whole lot of options for people who would want to come out to Virginia. (I'm in Charlottesville.) You could offer different tours at different price points. If you're going to run the parkway/skyline you could do camping/hiking tours, hotel/tourist tours and hard riding distance tours. I think a battlefield specific tour would be a pretty niche market, there are lots of other places to take a motorcycle trip in the world - the alps, New Zealand, Mexico - if you want to make a trip that will make money, you need to design a trip that will pull people in. There is a lot to see and a lot of places to ride in the area.
Sounds like most tours like this have an option to buy somewhere in there, would you be about that? Also, if you need a stack of new bikes on the cheap you could always pick up a stack of the now defunct Buells, which should be going cheap... I love motorcycling in VA and it's a wonderful state for it. I'm interested to see where this goes. Actually, very interested.
