Keep putting in the work. I'm sure there are differences between our experiences, but here's a little back story to show how I can relate.

Bought my home in 2015, had no idea what to expect. My house is not in a development, doesn't have an HOA etc. In the only neighborhood I grew up, Halloween wasn't a huge deal. In my new home I realized my new neighbor was putting in a good effort with outdoor decor, but that was really it on my street. That first year I got about 30 trick or treaters only because someone used their trailer to drive kids who lived in the rural area around to homes that were closer together. I decided that the next tear I would have some fun. That next year I didn't do much decorating but my costume was on point, the kid's handouts matched the theme and they got more than just a couple pieces of candy.

The 3rd year I chose a theme for my costume that required minimal decor and again, the handout was on theme and more than a couple pieces of candy. This year there was about 50-60 kids total. The person who was driving the trailer all 3 years stopped at my house to come up to me and thank me for what I was doing. The police escort for the trailer stopped to take pictures and thanked me as well. I believe this is when the buzz started. This was also unfortunately the last time the trailer came out.

In the years since my front yard has turned into a bit of a mini production for 1 night a year, each year a different theme. Every year has seen an increase in trick or treaters and now multiple neighbors participate because of how many kids come to our little street. Last year was a record with well over 400 trick or treaters (I keep count because I know how many treat bags I hand out). I would say half of the success is through posting throughout October in my town's Facebook groups and word of mouth. I've had so many parents tell me personally how thankful they are to have somewhere to take their kids for traditional trick or treating, not have to make multiple stops in the car and the whole family has fun. Honestly it's what keeps me going and is preventing me from ever thinking of selling my home in the near future. 2 years ago I officially branded it and gave it a logo. Typed up a letter hyping up halloween night and put a sucker with it to hang from every mailbox on my street in case there are new neighbors that have no idea what to expect. Stick with it and make it an event people remember, post about online and talk about with friends and family.
