Making trails

I went for my first run in a week today (pleading sick last week with a measly strep). A part of the trail was closed off because they were replacing a major storm drain. Not on the trail, you understand, but beside it. I figure they were worried walkers and bikers would suddenly lose their balance, tumble down the bank, and end up head first in a pipe. Unlike the case with cars, no alternative routes were suggested or provided, just a big yellow sign and a big barricade. This despite the fact that this trail is thicker with commuters at that time of day than the major arterial thoroughfare (or so the city calls it) that runs along in parallel. Unlike the case with cars, we all ignored the sign and hopped the barricade. Pedestrianarchy.
