There are definitely pros and cons to the bus.
Pros: it's cheaper. You can do stuff while you go places. You don't have to drive - which for me is a big one, I hate driving.
Cons: bus drivers aren't super nice (they tell you something and get annoyed when you don't hear them) The seats aren't comfortable. The stop-and-start action of the bus could make one nauseous. And if you don't know exactly where you're going you have to pay very close attention to where you're going so you don't get off 5 blocks too early and end up wandering up and down a street looking like an idiot.
All-in-all it's not too terrible...Maybe I'll get some good stories out of it :)
And here is a picture of the beach I went to today:
