"I'm sure some people get tickets," Fronhofer says. "But I haven't, and I don't know anyone who has."

Twohig says that the changes from two years ago extend beyond the safety and the organization of the shuttle service. He now misses the camaraderie that the drivers once shared.

"Two years ago, the shuttle system used to be a real fraternity," Twohig says. "Students ran the thing and we all knew each other and had lots of pizza and keg parties. It was like some people were into sports, others into final clubs, so our thing was like a club for people who worked a lot."

At one point, he recalls, shuttle buses began to disappear from the garage, only to be found a couple of days later in Boston or points west. He says the drivers were getting the keys at night at taking the shuttles out for joyrides or using them for transportation on dates.

While the job of driver has changed since he left, Twohig says that has not stopped him from trying to make driving the shuttle an entertaining experience. He tries to spice up the rides for passengers by blasting heavy metal music from the radio and engaging them in cheerful banter.

"To enjoy the job you have to enjoy meeting people," Twohig says. "Even when you're alone on the bus for a while, you still have a chance to think or just reflect on life."
