I'm really into walking with my dogs and exploring my neighborhood here so I've found money I'd say 4 or 5 times in the last couple of years. The most I found was a $50 bill on the ground by a bayou. I typically find cash on Saturdays and Sundays so I assume it's people/teenagers coming home drunk and dropping it.
I've purchased my last 5 cars on the phone and got AMAZING deals on all of them. That's all I'll do from now on. When I go to the dealer I'm there for 15 or 20 minutes then I'm out with the car, no fuss.
