A man rides into town on Friday and three days later, leaves on Friday. How does he do it?

it’s the weirdest thing I’ve ever heard 
any clue?
Is his horse/bike/car named Friday?
Friday is the name of his horse.
I’m picturing Sgt. Joe Friday from Dragnet carrying him piggy-back style in and out of town, dropping him at the city line, and saying, "And stay out!
Arcidee and DrLisa are right, Friday is his horse!!
