Up in smoke

I think I ran a little too extreme yesterday. My right knee has been bugging me. Fortunately I plan on not doing any running for the rest of the week, so I should be good.
An hour or so before leaving work I noticed some smoke rising in the distance forming an interesting mushroom cloud. It looked like a major fire was happening to the south east. I soon learned that it was a condo complex being built near where I used to live. Unfortunately, Cameron, a co-worker and friend, had put a deposit on one of the units of that complex. Well, it’s gone now. I’m looking forward to what the newspaper has to say about it tomorrow. Arson or natural causes?
