A few years ago I went to Costa Rica and had planned to take a tour to view a volcano. Circumstances changed and I had to cancel the tour. I was so disappointed that I didn't get to see a volcano while I was there. But, as luck would have it, I had a window seat on the plane home and flew over not one, but four different smoking volcanoes. I got a fantastic view that I wouldn't have had on my tour. I still want to go back, though, and see the volcanoes from the ground.
