Seems like many cities in the western US fit the bill but here on the east coast I think Richmond, VA stands out as having a ton of singletrack accessible right in town. Also, Charlotte, NC has the "Backyard Trails" system and while many of the trails here in Atlanta aren’t official, we have dozens of miles of Singletrack inside the perimeter.
I second the Back Yard trails, but that’s only 11 miles. Charlotte has a few trails systems from what I’ve seen on the map here, but I’m not to terribly sure there are enough and close enough for it to be a top city. I think Asheville would be a top North Carolina contender.
I wish I was into MTB when I lived in Atlanta now that you mention it.
