We see deer all the time on rides around here, even in the more
populated, suburban areas outside of Philadelphia. Where there is one
deer, we always remind ourselves that there might be a mate, or fawns.

There is a story in one of my bike clubs about a member on a suburban
(as opposed to rural) ride who was struck by a deer that suddenly
bounded out of the woods and tried, unsuccessfully, to leap over her.
