Building your own trail is fullfilling. It is something I definately don't have a chance to do. We have....too many trails (ducks on coming rocks and boulders)...seriously unless I start breaking laws or rebuilding old trails I don't have anything to play on (I don't drive so I can't leave town, which there is TONNES of space)...the chance you have would be more fun then riding imo. You can build 3 or 4 AMAZING trails...especially rolling and flowy. I will take a well built single track that rolls and flows (with some manmade...come on now...I love man made haha)...anyday over dh...
