During the summer of 1989 I took a trip to Canada traveling with my parents in their brand new motorhome. One of the stops we made was at the Athabasca Glacier which is part of the Columbia Icefields in the Canadian Rockies. These giant "Terra Buses" take passenger up onto the glacier where you can get out and walk on that ancient ice. That's my mom and dad in the photo above.
I occurred to me as I was writing this that back in 1989, Wikipedia didn't exist. Now there is something to think about.
