Actually, I do know who the owner of the land at "360" is as well as the gentleman that the company employs to monitor/maintain it because I do business with them both and regularly hear about all the damage that is done out there. I also know it's posted with No Trespassing signs at every conceivable entrance and that both Fort Worth and Arlington police regularly show up to issue trespassing tickets.
So if you, as many others, have "heard" that the land owner is ok with you being out there, you've actually heard wrong. You aren't the first person to have heard that rumor and probably won't be the last.
You're right, that group does regularly go out to help those that get stuck wheeling illegally, Joey and quite a few others go out nearly every night, good on him, but to act like he respects private property and the rights of property owners is a joke.
