Recently I went on a vacation that was a huge grand tour - a train ride into a place followed by nearly 2,000 miles of driving all around seeing everything there was to see. Planning the whole thing was a huge effort. About 60% of the trip was pretty well filled in - specific things to see and do in the various places we were going. About 40% of it, though, was "go here, find something interesting to do, and do it." Amazingly, we were always able to find something interesting or fun to do, and the trip worked out great. Some trips you plan down to a T, and others you just sort of go with it. As Matt Weatherford says, if you go to Vegas, you're either Gambling or you're Gamboling. FOCUS: What exceptionally good (or exceptionally bad) experiences have you had while traveling without specific plans? What have you discovered, or done, that you never would have otherwise?
