There's lots to like about my neighborhood -- many trees, near the greenway, generally kind neighbors. No pressure of trying to keep up with the Joneses because none of the Joneses are very fancy. However, I do live fairly close to public housing. Unfortunately what that has meant that there can be some issues with gun activity. We frequently play the neighborhood listserv game of "was it fireworks or gunshots?" Last year we came home from a vacation and found a bullet laying in the driveway. A dogsitter once had a very nice bike stolen off of her car that was sitting in the driveway for a total of 30 minutes.
The only other complaint with my neighborhood is snakes. My neighbor up the street got bitten by a copperhead last week and had to go in twice for anti-venom treatment. I have found several in my yard over the years. I don't want to forbid my kids from playing in the back yard, but it does make me kind of nervous...
