I saw this older gentlemen during the winter with his cane, and more interestingly, wearing his helmet. Winnipeg streets can be treacherous in the winter as they are covered with ice and snow. So a slip could lead to a head smack on the sidewalk. A helmet would help in that scenario.
Today I saw the old guy walking by again. And lo and behold, he had his helmet on. The sidewalks are dry and clean. Very good traction. But this fella isn’t taking any chances. He is really protecting that noggin.
