I rode the High Bridge end yesterday on fat tires. Started out with one main worn in path about 20" wide give or take and for some brief sections there were two worn in paths that size. A little bumpy but not terrible, and I could keep a reasonable speed for a couple miles. It steadily deteriorated the further I went until around the 2.5-3 mile mark where I had to do a walk/ride combo for a bit to make it to the bridge over the KL gorge, where I threw in the towel and dropped down to the gorge road.
Heading back on the gorge road there was a nicely worn in path around 24" wide or more that was smoother than the one on the Columbia trail and pretty easy fast riding.
Tried the Taylor Wharton green-way trail on the return and it was not well worn in at all with just a few sets of footprints. Was fun slipping and sliding down the hill, but had to walk at the bottom once I lost the help of gravity and bailed on my plan to try and make it to solitude falls.
Train-tracks in town were not ride-able at all. I thought the 4 wheeler and moto crowd would have made a path by now....damn slackers.
Overall, not the most fun riding, and hard to tie together a decent loop, but better than nothing I suppose.
