There is an application called Nextdoor that is supposed to link community members. It is paid for by advertising, and there are some things I don't like about it, but I have found out important stuff related to our neighborhood in Las Vegas.

One of the nice things is a Treat Map where we can indicate whether we are giving out halloween treats or not. The comments about it are very interesting - people talking about how many trick or treaters they usually get. Apparently Halloween in the Las Vegas suburbs involves parents loading a bunch of kids in their pickups and driving them to the better-off neighborhoods so they get better treats. The parents park the trucks and wait for them.

One of the commenters recalled how in the 1950s in California one of the dads set up a bar in his driveway to hand out drinks to the parents who were walking their kids house to house. I'm wondering if the parents in the pickups would get out and line up for open bar.

Some of the neighborhoods near me in Colorado have Nextdoor, and I have tried to sign up for it here, but the app won't let me. I think one reason is that there are no businesses in this rural area, so we are theoretically out of range of potential sponsors, but also when the near-by neighborhoods set up their area, they drew a small polygon that didn't include my area, so the online app can't 'find' me to link to theirs.

One of the complaints about it is people initially thought it was how they would communicate just within their neighborhood, but the area covered is quite large, so it's not as specific as they'd hoped. Once again, that goes back to the advertising sponsorships.
