iMTB Rockstah
In order of difficulty of descent easiest to most challenging (in my opinion): I don't count Cholla or Mathis because neither should be a descent.
Meadows - flowy goodness, berms but zero chunk
Rock-It - Low gradient all the way. A little bit of everything - turny goodness, straight ahead chunk, techy little climb, a couple of tiny jumps
Lynx - A little steeper and faster than Rock-It with some little ledges that can mess you up. Pretty straight though.
5-Oaks - Steeper with a few ledges, some ruts and braking bumps up top. Challenging roots, rocks, ruts and stairs near the end
Mentally Sensitive - Steep, awkward, rutted, loose
Stairs - Bigger chunk, but pretty straight. Steeper than Rock-It
Car Wreck (with the drop) - Steep chunk in spots with big holes. A 4ft. must huck that has a tame ride around. Off camber chunk at the bottom leading into the actual wrecked car.
I think that's it for legal trails.
Fair enough. I concede to the expert. The only trail in Aliso I have crashed on is Lynx ... five fukin' times. That bitch has my number. I am obviously not riding fast enough.
