Bicycles -- used ones.
Several years ago I lived about 65 miles from work. The engine in my pickup threw a rod. I didn't have the money to fix it or buy a car that would handle the 780 miles a week.
I moved into a spare room with a friend that was about two miles from work. I walked to work until my next day off, then went to Wal-Mart bought a bicycle. I rode the bike to work until I could buy a car.
