      Was a great trail that is now super rutty and has tons of washboards since it's been ridden into the ground. Sort of a shame. If BMA/IMBA are going to be eventually working this area, let them start with this one. If they are going to do their thing and mollify trails, they might as well do one that is super accessible to the masses. DA will be one of the first trails people ride in LHOHV since it isn't nearly as difficult as the lines in the Bon Scott region. After working on DA, maybe that will convince BMA that the double blacks shouldn't be worked so hard as to become single blacks. Lunch Loops in GJ is a good example of how to maintain the trail of an area without making it easier.

      Update: a decent amount of work has been done to this trail over the last year. A lot of the berms have been built up and the top is a lot more fun even if the traction killing sideways rut bumps are a bit annoying. This is probably one of the funniest, flowiest mid-level black downhill trails here now and a great place to train your downhill skills on since wrecking here is alot more forgiving than many other similar level trails here. On the downside, the mid trail hill drop wood is getting a little chewed up and the old classic ending drop has been blocked off probably due to erosion.

      We hope you've been enjoying Trailforks!
