I need to know what happened. However, I definitely would have defended myself and pulled something out. Let that dumb mufucka swing on me!! I woulda cracked him on his knees and watched him crawl back in his house and wait for the police and show them the footage. The city needs to inform homeowners if work needs to be done on their property. In fact, work was being done on my block and I saw several neighbors yards dug up. They didn't hit my yard though.
