Oh lawd. I have to be the first person to respond to this...
Ok, I dot mean to sound like an asshole. Seriously, I just want to give you some advice
First off, saying 'seeking squatters anywhere' is going to raise a red flag to people on here. Most people who squat are going to look for people in a certain area, or at the very least, want to find people who are around them in order to get to know them first. I'm not really a squatter, just know a few, and usually are not going to just let anyone they meet on the internet directions to their squat to meet up.
Secondly. Saying that you will take Amtrak to them is another red flag. I dont really want to explain why, because it is very, painfully, obvious.
If you are serious in this endeavor, I would seriously advise asking to message with squatters and possibly meet up and talk about squatting somewhere neutral, like a park or starbucks or something. Or just message people on here. There are plenty of people who would love to have more squatters join the ranks.
My point is, your post comes off as sounding like Law Enforcement, or at the very least, someone who has absolutely no idea what they are doing. My opinion also is based off of your train hopping post.
Yet again. I'm not trying to be a dick, just giving advice.
