From Sea to Sea: An Exploration of Canada by Bicycle
Another thundershower. I became quite adept at dodging these. I could judge whether the were heading above me, below me or were going to hit me dead on and seek shelter accordingly. What was really cool was that at the very center of the storm the clouds would bubble and boil like dry ice does when you add water to it. This particular cloud reminded me of the storm that came up during the final battle in The Gostbusters movie.
