Buses are too wide to use the driveway at Purdue Memorial Union, and Grant Street is only one lane each way, so we have to use the side streets nearby.
This link [reindeershuttle.com/map/north-grant] will give you a Google map with the coordinates of the pick-up and drop-off location (40.425858, -86.910204) for buses. You can use this as your destination in Google Maps; click “Directions” after the map loads.
The target location is north of the Grant Street Parking Garage, just after turning off of Grant Street, facing east. Park safely before the Parking Garage entrance as close to the curb as possible.
