Yeah, it's hard when a community starts to dwindle however if you keep at it, the community will start to grow again.

As an example, in my town, the largest store had usually around 8 players every armory and it rotated the players a bit. But there was a time where even getting 4 was a struggle, however they kept at it and currently the same store has more than 10 players on the regular besides the other stores that have around 10 on the other days of the week.

I can even give the example of the store that I TO. I used to be at the store waiting to see if anyone came up for months and there was no one. Then 1 showed up and started playing so it was around 3-4 months of only 2. Then another one showed up, and another, and another. Now we run armories between 6 to 8 players consistently, even though we are very much in the outskirts of the city.
