COMPLETE walls?
Do they count as "complete" walls if they only go down to about a foot above ground? The bus shelters around here have 3 1/3 walls - they're rectangular with the long side facing away from the street having just a little stub on either side, along with a roof. But they don't extend all the way to the ground, I assume the gap is so the driver can see if there is someone in the shelter if they're not paying attention and don't notice the bus until they can hear it.
