Okay, it's not technically a commute, but on days when I work from home, I usually go for a 20km ride before work. This morning, I did a route I haven't done in a few weeks. Part of the route is on a MUP that runs through the city's river valley - beautiful trail and good climbs out of the valley. Problem is, there's some construction in the area with trucks and equipment driving along and over the trail. They've built a temporary boardwalk over the trail to protect it, but whoever built the boardwalk obviously aren't cyclists, as there's a large section where the boards run parallel to the direction of travel for trail users. The gaps between the boards are wide enough to swallow a narrow road bike tire, and that actually happened to me. Thankfully, I was aware of the potential danger, and was riding very slowly, so I didn't fall off my bike, and the wheel wasn't damaged. Still, it made me irate enough to write a letter to my city Councillor and provincial representative, as well as make the local bicycle commuter society aware of the problem. Grr.
