You walk.
A LOT.
Pullman didn't have a bus system like CyRide. I lived in a dorm, and had a full meal plan. A large percentage of the students at WSU were from the Seattle area, so there was a "rider board" where you could put your dates & destination, how many passengers you would take, and how much for gas....that's how a lot of us got home for random weekends. For major breaks (Thanksgiving, Christmas, Winter & Spring) they chartered Trailways buses that went from Pullman to Seattle's bus depot, and your family picked you up there.
Lemme tell ya, it was better than taking the horse & buggy...![]()
Or swinging from tree to tree...
