'85 was built by the Fat Tire Farm and named to commemorate the year the Farm was founded. It’s a natural and raw trail that gets progressively steeper the further down the trail you go. There are some natural features, but nothing you can’t roll. The final section requires commitment to steep chutes with catch berms

      Quite a haul to get up to this trail from the main lot. It’s fine. Not worth heading all the way out there imo

      Do not stop in this section. I was swarmed and stung by 20+ wasps
