How do you make it worse, kimba?
The most annoying things on the Miami Metrobus tend to be born-again Haitians popping on to preach about how Jesus is returning next Tuesday, loudly and in Creole. This happens to a lesser degree in Spanish and English.
This happens seldom during my rides. It is tolerable and still beats walking or driving. The bus is nearly always empty enough where and when I travel to get a seat.
Smelly fellow passengers are worse than loud ones, but they are fewer in number. Mostly, both the Metrobus and the Metro rail are adequate and useful.
