Replying to My crazy day

So at my school it's finals and it was my study hall and so I got to leave an hour and 45 mins early. I don't drive but some upper class men and me decided to find stuff to do. In my town there is this abandoned shipping and semi place. And it is seriously the most sketchy place ever. Graffiti, bottles, trash and torn up couches. Their is a rumor that tons of homeless people live there. So we went to go check it out and their is this hole in the brick wall and in this little entrance way and their are mattresses and their is a little crawl through from there into the big main part. We didn't go in. We left and went to Taco Bell. After that we went back to the place and drove around back and their was a truck waiting and it drove towards us so we whipped around and peeled out of the place and sped down the road going like 70. We thought we were just paranoid and we didn't see the truck then out of nowhere the truck pulls right behind us. It had to be pushing 90 to gain on us like that. Also it was snowing so the roads were messy. We blew stop signs and stuff and we ended up losing him on back roads and a housing development. So we have noo idea wtf that was about. But it was completely badass at the time cuz it was a legit car chase. We're going back tomorrow and I might actually go into this place alone strapped with a gopro. If this happens I will put up video of it. I have no idea what to expect. I'm just worried I might get rapped or stabbed or some shit. Im pretty sure a meth lab was busted here at one point to? Anybody have any thoughts/ know trespassing laws? I'm 15 btw. We think that's what that guy was there for but their are no signs for trespassing or anything. This is all true. /story
