Right now, this is the schedule to the furthest point east that I know about. I am modifying the schedule, so check back to see the updated version. Remember, all schedules are as convenient as possible!
Notes: The SAM bus will make a timed connection with the Mountain Express (if you get ahead of schedule, which means if you catch the 3:00 SAM) if you tell the SAM driver that you are transferring to the Mountain Express.
