Montana, like every state in the union, has an enormous problem with meth.  It is cheap to make, highly addictive and readily available.  There are signs everywhere, meant to discourage people from taking the first hit of meth.  I found this hand painted sign on Higgins in downtown Missoula.

I love the 90 minute hike on Waterworks Hill.  When I reach the top, and am facing east, I can see the Rattlesnake, and it is so very peaceful.
