Awesome!
I've been hit and miss over my 17 years of working, though only fully stopping for one year when I had a 20 mile commute, but several stretches dropping down to only a couple times a month. Last summer I got shamed badly by sucking wind on a company sponsored lunch ride. Since then I have steadily built up to about 80% biking. The last two skipped days were due to running 7.5 miles home after biking in and needing to drive back in, and then a week later getting a flat on the way in and having to repeat the run home due to forgetting my bike tools at home. Reading MMM added a layer of devotion I needed to stick with it. Now it is not too bad to bike in, bike to ultimate frisbee at lunch, then bike home for a 24 mile day plus the half hour of frisbee.
I have not taken the step of selling the spare vehicles, might never. They are not worth much.
I don't think I have netted any actual savings, but am in much better fitness/health. I have sunk about $2.5k over the last 10 years in bikes, fenders, lights, clothes, tires, tubes, locks, tools, pumps, helmets, shoes, wheel, etc. I am just shy of 5k miles in that time, so about the same 50 cents a miles I figure for vehicles. I also eat more due to all the burned calories, but I don't really count that.
