I found a $20 bill riding my bike to work. I continued to search for money along the four-mile stretch to the 
office, but found only a few pennies and a Wal-Mart (WMT) shopping card with a 20-cent balance.
Here’s how the numbers break down.
For every four miles, I will average finding just more than $20. I can cover four miles in fifteen minutes, but not every 15 minutes. If I know anything at all about the law of diminishing returns, that’s a pretty long ride each hour. So we’ll say just two four-mile stretches every hour, eight miles an hour, eight hours per day. A guy who can’t ride a bike eight miles an hour shouldn’t be working, anyway. Eight times eight is something close to 64 miles per day. Averaging $20 every four miles, that’s 16 $20 bills I'll find, or $320 per day, which is more than I’m making now. Sweet!
