Below is a map of the route.
The downside was that I broke my chain. Twice. The first time I had fixed it in record time, but I had routed it through the derailleur a little wrong (the chain was on the wrong side of a retention tab). After I fixed that, it didn’t look right, but I thought/hoped it would be enough to get me home. No such luck.
After it snapped again I had to go chainless back to the truck. I took a couple DH trails with no chain, which was pretty fun, but the setbacks meant I was late leaving which impacted Sox a bit.
Now to get my bike fixed.
