I've been there and before we could get everything unloaded we were run off by a Galveston County police, this was about a year ago. I have a friend in Danbury that hunt there often I'll try to get some info from him.
The last time I went there to do some shooting I got run off by a A&M cop. He was pretty cool and let us finish but asked us not to come back. So, I ain't been back.
