Wouldn't mind seeing the Grand Canyon that way. Do you have a link I can take a look at to see if that have an origination point anywhere near north Florida?
One of the highlights in the Colorado trip we were looking forward to was a train ride along one of the old mining routes between Durango and Silverton.

But I think the only way we are going to be able to make such a trip is to sneak up on it and plan on leaving like TOMORROW. Not give Murphy's Law any time to make it's own plans to wreck ours.
