I'm in Dallas as well, and I hear gun shots daily. New Years/4th July absolutely sound like a war zone. I found a slug next to my trash can after a 4th celebration a couple of years ago. Not a shell, the actual slug. I keep it on my desk as a reminder. My fur babies are not allowed outside on those nights.
curious to know where you are in Dallas if you don't mind. I'm in Oak Cliff in the Winnetka Heights neighborhood. This past New Years and July 4th were especially bad, people were double parked on I30 on the bridge to downtown, and the gunfire and fireworks were nonstop. DPD has basically given up, there's going to be a tragedy on day and everyone is going to be like "how could have this have happened!?".
