Buses. It takes ages to get to somewhere. Stuck in city traffic, doing long detours everywhere.
International buses are known for attracting those who can't afford the train. Meaning the third world looking folks, they almost bring chickens, freshly harvested vegetables,... aboard. A culture shock. Still takes ages and the frequent stops in the next cities prevents you from sleeping.
Calgary Transit. It is NEVER on time, constant breakdowns, they close routes down regularly, it's overpriced, its dirty, not to mention the transit cops care more about fare-evaders than keeping it safe as we've had stabbings, assaults, fights, etc even in board daylight.
