I looked at taking the bus before I started riding as a way to save money on gas. The local system is arranged like spokes on a wheel, with Lancaster city in the center. I'd have to take one bus into the city, then transfer and take another bus out to where I work. Due to the horrible scheduling, the bus into the city arrives 5 minutes after the bus leaving the city. I'd end up waiting at the bus depot for 45 minutes. Then, due to some ever better scheduling, I'd miss the last bus out to my house in the evening.
I've suggested to their customer service people that they install a route or two that cross the spokes, but they don't have the money.
To the OP: I love how SEPTA wants you to use your bicycle to get to work, and then restricts bicycles on train to non-commuting times.
