I'm going to sublet my $81 monthly parking stall at work. I've been going to night school twice weekly, so I need the car. Whenever I bike to work, it's like paying for a stall I don't use. So starting next month, I'll park on the street at work on night school days and bike in for three days. It's been raining lately, so that'll be a challenge.
It's six miles one way, which takes 18 minutes by car on a good day, 28 min on bad mornings. On bad days going home, it can take 45-60 minutes by car. On my bike it takes about 32 minutes. If I ride in traffic, it's scarier but a faster commute.
