They’ve adapted remarkably well to urban environments it seems. In Chicago they regularly use train lines and greenways along the both branches of the Chicago river to get around. And there’s loads of parks, cemeteries, and other green spaces. Deer seem to do well in the city too. The cemetery I used to live by (Rosehill on the Northside) hosted many deer. This is a cemetery with dense urban residential areas on all four sides, but it must have been large enough for them and there’s lots of quiet neighborhood side streets around.
