When I was driving beaters, I carried enough crap, tools and hardware to build another car... on the days I was thinking it was iffy (started slow the day before, brakes felt low), I threw a bike in the back. Never walked. Now, when I smacked my Scirrocco into the back of an AMC Concord just right and I killed it, I rode my bike to BOTH my jobs, first one (8-4:30) was 10 miles away, the second (5:30-11:00) was on the way home, about 7 miles away. I did it for 9 months... It sometimes gets down to the low 40's in February here. I quit the second job when I had enough money for a better beater.
