it usually takes me an hour to get to the office, 40 min during summer, this is to cover about 30km.
The problem here in Portland is I have between an 11 and 13 mile commute to the office downtown. 18 to 20 km.
To use the bus or light rail to and from work, figure out how long it would take to drive, then add on an extra hour in the morning and an hour and a half at night.
I might pay $20 a day to park, but I get back 2.5 hours a day in time. My time is worth far more than $8/hr.
