Nothing specific, but probably something wider than a regular sidewalk with
curb ramps but not a dedicated bike/exercise trail.  I was just looking for
things to flesh out the example, and did not mean them as a very serious
place to start for safety/quality ranking.  As this shows, good
descriptions, and pictures would be important to get reasonably consistent
results from differing users.
