I need some info on a spot I keep seeing 4x4s go into..

 

I'm in Pearland, but I don't really wheel down here, just in the sand down south. Where are they going?

 

At the corner of herring road and cornett.road right past the.train tracks... On some maps it pulls up as amaco industrial road some it.doesnt show anything.. Im on my phone or I would post an aerial... I have never seen any signs so I dont know if its legal to go back.there
