I use the STA trails a lot.  They are a great asset to Anchorage.  But I agree with the writer of the article.  Too much of a good thing is not good.  Too many trails is not good.  Especially for animals.  If there is no place for moose and bear to be buffered from people in our parks, these animals will just be more stressed, and potentially more aggressive.  Especially in the spring when they give birth.  You can't keep bear and moose out of our parks, so for safety concerns we need to give them some space of their own.  I've got to agree with the comment about too many trails.  It's time to give it a break.  And stop cramming endless singletrack, Nordic, archery, frisbee golf and social trails into our parks.  Let some of the land in our parks be ... park land.
