Here in Kitchener-Waterloo it has been a long, cold and snowy winter that has not been conducive to walking. Normally I would have had one of my classes walking off-campus several times, but so far this term conditions have only been suitable once. One such condition is that the temperature must be above -12 degrees Centigrade. Thankfully there has been a hint of Spring weather ahead and the walking can recommence.
