I only know 1 of my neighbors by name, and 2 of his kids. I knew another fella, but he moved.
My neighborhood is about 60-70% black so I'm a minority here. Nextdoor family that I'm cordial with is alright, drives an early '70s Impala "Donk" on 24s. He borrows my tools and I fix his kid's bicycles, he brings me burgers, brawts, and pork chops when he's grilling. We shoot the shit on occasion, I know he's got at least a hand gun in the house, just from conversation. I'm sure he's seen me carrying enough rifle cases to and from the Jeep to know I'm armed too.
I was concerned about him at first, pretty sure he was selling at least pot from his home, had a lot of random visitors that would stop by for 5-10 minutes at a time, all hours of the day. And he was skunking up our end of the street from his garage most Saturdays. Now with medical marijuana legal, and him having some in laws move in with him, his business has really slowed down if not stopped all together.
Neighbors on the other side are young, Caucasian, and either still in or just out of college, it's hard to tell there's at least 4 that live there fulltime, maybe 6 total frequently there. They're all inept at life, I've fixed more flats for them than I've cared to, rescued their dog from the street half a dozen times, offered advice on vehicle issues, etc. I'm stereotyping, but based on their appearance and noticing one wearing a shirt for one of the state's private liberal arts schools, I'm sure they're quite liberal. However, we were both hit by a "ding-dong ditch" bandit a couple months back, someone ran up beat on our front doors and ran away, caught them on my ring camera. I went out to investigate with my 870 that's got a Surefire strapped to it. Perpetrator was long gone, and my young liberal neighbors were freaking out, they sent one sacrificial lamb out to check, the rest huddled behind their door. When they saw me with the shotgun, they were all relieved enough to come out and see what was going on.
Neighbor across the street is always fighting with his cow of a wife. They're usually half drunk and yelling at each other. They're white trash, and have a toddler that's usually playing in the street.
Neighbor directly across from me are a bunch of college age girls, all renters, or maybe one of their parents bought the house. They keep to themselves, but yard work only happens on weekends that one of their dads comes over to do it.
So I don't see myself starting a mutual assistance group in my neighborhood. I fear if anything, it'd be everyone hoping Lee assists them. I'd help out my ex-pot dealing, donk driver, neighbor, we've got a good relationship and in general he's a good dude. White trash is on their own, all of the college kids are pretty much SOL too.
We bought 115 acres of swampy woods, about 30 miles away, so we'll be building and moving to our own compound, where the Mutual Assistance Group will consist of myself and SWMBO, maybe some livestock and a dog.
