When I interviewed for my now present job in Idaho falls, of course I did a cache search and saw that this one as literally outside my office window. So during a break I went for it - but did not find it. I searched a few more times since taking the job here but never did find it. Others had the same fate and eventually the troll that used to live here was evicted. So I decided to hide a replacement.
So come and visit the new troll. Watch for running water but you need not get wet (it is dry but can be icy in the winter). At certain times of the year you can watch Bald Eagles and/or Ospreys fishing the river or nesting on the other side.
