      		 If anybody finds a Garmin Fenix 6 with a green band, I’d love to know. I apparently got too stoked on some turns and it popped off. Other than...

      		 Very dry and loose in a few of the switchback turns, but fun as hell! Views for miles (if you can slow down enough to take them in).

      		 Upper section is holding out nice. From NUT to lower is quite dry but still riding well.

       Top to bottom ridgeline exposure, left, right, or on both sides of you. Fast, man-made woops and rollers and very steep, tight berms that require commitment. If this trail was rated black diamond I would agree with that over it being a blue. Overall, well built trail and definitively worth exploring! We climbed "4 the boys" from the ski area parking lot, then took the entire Freund Canyon trail around and opted to take this back down to the main view point area. Roughly 14 miles, easy pedaling up, fast and steep down. Managed to ride over a rattlesnake and watched it strike my rear triangle while on the Fruend Canyon trail so keep your eyes and ears pealed!

       Well built trail. The berms are so steep and so tight in sections I agree a black rating may legitimate. Freund descent is less technical

       This trail definitely does NOT rate a black diamond IMO. Anyone reading this who is new to the area and is trying to decide if they should go down Freund or Rosie should go with Rosie for the views if nothing else. The exposure is typical of Central WA trails - all technical features have ride-arounds - beginners may want to walk through a couple of the steepest switchbacks

       I woukd say most of this trail is blue, and I would encourage any intermediate riders to ride it. But, as previously stated, there are some very steep and tight berms (I dismounted for 4 or 5) and there are a couple of spots with significant exposure. But it is nothing to be afraid of, you can dismount as needed. This is an extremely fun and well-built trail!

       Can I really not edit my spelling on that previous comment after the fact?

       In its current blown out condition it is a black in my opinion
