Wonderful Run. Innie is a great trail. The first .5 miles of Outie is a narrow drainage/runoff that is rough on the ankles.(I would recommend just turning around and running Innie again, instead of going around as it would be the same distance)
North Porcupine is Sun Exposed and used more frequently for MTN Bikes(Use Caution)

Super dry. Oaks are starting to encroach quite a bit so keep your head up… or down. Still super fun.

The lower half of Audi is in very good dry condition. It's used as a connector from North porcupine to buckhorn for people doing a big loop from the town of Carbondale and back to carbondale. The uphill section to where connects with Indy the trail is almost non-existent. There were two tracks coming down it the upper mile is so overgrown you can't even see where it is sometimes. It would be a really great trail if it was maintained but this trail is not had maintenance for some time. And the trail is nothing more than a small narrow gully for where the rain goes when it rains hard. Lot of maintenance needs to be done as trail before it's really rideable. I wouldn't even take a horse up there it was that tight and overgrown.

The lower half of Innie is a really great line and it's in really great shape very dry well used while maintained. The upper half of Inne, though there are people that have been riding it up to the summit point it is heavily overgrown. Extremely narrow. There were parts coming downhill I had to get off because I couldn't see where the trail was and what condition the trail was in if there were ruts or roots or rocks. It's also very loose and Rocky on the upper section right before the summit. This trail needs maintenance or sections are going to start disappearing back in the hillside.
