    Gabrielino Trail (Kenyon-Devore Trail to West Fork CG)
    Jun 9, 2026 @ 11:01pm (America/Los_Angeles)
    Jun 9, 2026
    		Both sections between West Fork and Valley Forge trail camps are a bit overgrown. Some PO especially closer to West Fork. A bit of poodle dog. A few gully crossings require dismount. No deadfall.
    Gabrielino Trail (NRT)

    May 10, 2026
    		Redbox to the Switzer section is clear from any downed trees. A little overgrown in the first 30% of the ride but, overall, great ride today.
