That must be an interesting factor in their social customs. Yesterday at the market, there were pegasi who flew down to the stands they wanted to visit, and then back up to their . . . cloud. I saw at the hospital that they could come in through windows, and I've seen them perching on houses. What incentive do the ground-bound ponies have to accommodate that? What could a plain pony do against a pegasus burglar? They must have separate police forces to handle the different types of pony.
