No "that kind of antifreeze" is not illegal.  What are you insinuating regarding the voracity of my comment?  This was a widely publicized occurrence when the dog was poisoned.  I live less than 100 yards from that trail.  Further, regarding tent dwellers, I allowed 5% for the mentally ill.  I'll separate based on my own observations and experiences,  not your disconnected view of reality.  Today "homeless" has a whole new meaning that perhaps you have not yet been victimized by.
