About 8 mud bogs requiring dismount, and 8 or 9 stream crossings about half of which were unrideable by me today. The trail is quite haggard, rutted, muddy, rocky, and rooty. Most recent comment from September of 2023 sounds about right, except there wasn’t any horse poop today.

Total junk show, stream running down trail in spots, horse f’d as usual, six track, and the dirt is composed of 99% horse crap. Use Grizzly Bear x tension for a slightly better experience.

Torn to shreds from horse use. Not recommended for uphill travel. Downhill travel was fine
