Looks like one of the routes stops a mile and a half from home . That's about 10 minutes by bike . The bus driver showed me how to use the bus carrier . Mileage : 10.6 miles total , time spent about ... 2 hours , though it was almost 4 hours from leaving to returning home . 
Question: Why did the bus driver show me how to use the bus carrier ?
Because I didn't know how to use it .
