A technical decent with a few features throughout. Rocks faces are off camber but ride-able. Upper Grumpy has seen some recent work and is riding better than ever. Go ride it again, super fun trail that gains access to Lower Grumpy or Reverse Brazillian. Old school trail. Worth the ride, if you are up for it
Access Info
Starts off right near the high point of Econoline, start of Upper Grumpy also gives access to Stoked Proper and Stoked Chicken
