Encountered this fire truck on my way to work, with its ladder extended right up to the roof of the triplex. Didn't have time and didn't want to disturb the firemen while they were at work, so I didn't learn what was going on. Strangely, later that evening when I was taking the dog for a walk, I discovered the entire alley behind the house blocked off, to pedestrians as well. A problem with the power lines? A potential sinkhole? I'll try and find out.
Addendum: word on the street is that it is actually due to a conflict between neighbours over a sagging tool shed/garage in the back. One neighbour wants it repaired or torn down and called the firemen to escalate the situation. Ah, neighbours!
