If you ever get a chance to go to a National Enduro, GO!!  The one they ran in Maine last year went right by my house, I got to hit quite a few spectator points and worked a checkpoint.  It is unbelievable to see these guys going 3rd gear wide open through tight trees and nasty rocks & roots.  Plus it was about 50% 2-stroke!!!  Nick Fahringer was riding an obnoxiously loud Husaberg 4-stroke last year, great to see him on the 2!!
