OMG, I had a 1990 Rockhopper just like that one which I trick out in a variety of ways to make it the fastest all purpose bike around. Even hauled it on top of my old Landcruiser across the country to the Outer Banks. I lost it when I was bikejacked in Denver -- knocked off and the bike stolen, a great story.
I recall reading about that, I really hope this one isn't yours! It's obviously well traveled.
