So, here's my thoughts on this article, written by William Burr.
In the last three months, just on my block and the two on either side of me (that makes three blocks in total) I have personally seen evidence of the following fires:
Burned car - Monday night, July 18
Burned couch - within the last week July 11-18
Burnt dumpster - around June 12
Burned house, internal damage - June 4
