Roomsburg, of Muskegon, said he was with his father and brother on a drive from Grand Rapids to Muskegon when she spotted the unusual sight.
"We were all stunned and were like, 'did we really just see that?'" Roomsburg told WXMI-TV. "We had to slow down and actually drive past the guy again to get the video."
"When I first posted that, I just posted it to my friends. My sister told me to make it public and it would blow up," Roomsburg told Mlive.com.
The "driving" deer turned out to have been set up by hunter Mike Huntoon, who had been returning with his friends from a hunting trip at Camp Preach No More in the Upper Peninsula.
Huntoon said the prank started as a simple lack of space for one of the five deer bagged by the group.
"We thought, let's just have a little fun with it," the hunter said. "We have to get the deer home, let's see if we can create a little humor...and apparently it worked."
