I have had whitetail from SE and NE Washington.  Mulies from the sand dunes, waterville and the Glacier Peak Wilderness.   But, IMO nothing is better then a SW Washington Blacktail...Very mild and succulent.
I have always been fortunate to have one shot kills on relaxed animals.  No endorphins pumping in there bodies.  With the Blacktail they are Gutted and hung within 1/2 hour.  I let cool down overnight and cut and wrap the next day...
