It would have been warmer to catch the 110 bus from Trader Joe’s to Buckhead Station last night. But then this $5 bill might still be lying in that flower-less flower bed next to the sidewalk.
Not quite as cool as spotting a $20 bill swirling around in a little pile of windblown leaves at the top of an escalator at Civic Center Station about a year ago, but still worth that 15 minutes in the wintry wind.

In my nearly 30 years of being a “free range pedestrian” (i.e., no longer tethered to my parents), I have found, approximately, nearly $300 on the streets. My biggest find was a 100 dollar bill at the North Avenue station when I was a poor graduate student at Georgia Tech. Needless to say, I put that money to good use.
My most recent “big find” was $20 while walking back home from work a couple of years ago when I lived in Chattanooga.
The most memorable (besides the 100 dollar bill at North Ave) find was at the age of 11; my mother didn’t want to buy me an Atari game that I wanted, and I was sulking. As I hung my head, on the walk between the PX and Commissary (this was on the US Army base in Mannheim, Germany), I spotted a 20 dollar bill on the sidewalk. I picked it up and told my mom that I was going back to the PX and would buy the game on my own. Needless to say, it brightened her day, as well, because now I got the game, and it cost my parents nothing!
I think the best I’ve done is finding $20 at the top of the escalator at Civic Center Station. Other than that I think it’s been mostly ones and maybe a five.
I did once find $20 walking home from Metro when I was living in Maryland, but when I got it home and washed it off I realized that it was counterfeit, as the paper started to disintegrate. Guess that doesn’t count.
