I was putting some final touches on Johanna's Jake the Snake for upcoming abuse of it on the D2R2. I wanted to take it for a spin, so I rode it up through Cedar Hill Cemetery, out towards the quarry and nearby spooky environs. Much too my surprise, they're doing all sorts of crazy new construction at Cedar Hill. It looks like they're adding more ponds and that they've taken down a good 5 acres worth of forest (which, of course, make me a little sad). How did I miss this? I go through there pretty regularly, but it has been maybe a month or two.
And then (GPS is so cool!), I rode down through those other Cedar Hill trails and some of it appears to be legit singletrack.
