    		If you love riding a slight gradient for miles on a narrow single track with plenty of greenery this is the ultimate ride . Because at some point you're going to turn around. And head downhill. The scenery is awesome.

    		Should be noted that this trail is open to dirt bikes also, so expect more loose rock and ruts than on a pure non-moto trail. Otherwise dry and generally clear, overgrown in spots.

    		Downed tree towards the top. Check your speed coming down!

    		A few snow drifts need walking through. Trail is dusty in the sun and dry in the trees aside from spotty snow. Totally passable but Iā€™d give it another couple weeks.
