My mom did this in her PA small town and it worked. You can do it too. Today is a weekday and you may need to make some calls during business hours. If you live in an area where you even suspect a datacenter could be constructed your first task is to find out if there is one in the pipeline.
Next you need to find out if there are any public forums coming up, and when they will occur.
In this process you may find others who have already done much of the work.
If you have good organizational skills and can call and navigate local governments finding these events, making lists and suggestions of dates and places to show up can have a big impact.
15 people with signs is basically a nightmare. If the 15 also planned something to say in unison even if it's just "NO Datacenter" that's even worse.
It's easy to get all kinds of people to come to these kinds of events. They aren't very risky. It's fun.
Really finding the when/where is the worst part.
