Public transport is a great thing for so many people. It's a relatively affordable and accessible option for people to get around their city or town without having to own a car or beg a friend for a ride. It makes life easy for so many people. The only drawback (or maybe it is a perk, depending on who you are) to public transportation is the "public" part. Being a public service means that all kinds of people from all necks of the woods can come and use it. Which can be an entertaining thing. Sometimes even actual critters end up using it, probably not on purpose, though. Funny and unusual sightings on public transport can make the trip all that more exciting, or maybe nerve-wracking.
