I've seen deer grazing along eight mile near that WJR building [[although i think thats oak park?. I've also seen dead deer along southfield freeway in detroit. so if their not downtown yet, their definitely on their way. also if a coyote can live and raise pups on the grounds of fairlane mall[[that was 7 years ago) i'm sure deer can find a way downtown. Especially with the explosive deer population and all the abandoned railways and vacant land that leads to the river, its just natural.
