One of my home ownership dreams was to have a massive DH/XC track in my backyard. Unfortunately, there's only so much you can do with 1300sqm. Also, the wife had to approve of it, so it needed to blend in and be a bit of a 'garden path'. Still a little more work I can do to neaten things a bit, but generally I'm pretty happy (and so is she!)

So far I can only call it a pump track if I'm riding it counter-clockwise, but that's me, not the track; a bit more practice and I should be able to ride it chainless in both directions.
