I bought a new wallet on Saturday and immediately transferred all of the contents of my old one to the new one. Since I'm not one to get attached to wallets, I threw the old one away. And today I realized I had not taken the cash out of it. Sigh.
Luckily, the trash was still in the kitchen and I didn't have to dig through very cold trash in the dark (or fight the raccoons for it). The wallet was at the very bottom, but I saw it through the bag and did not have to dig through an entire bag of trash to find it. Well worth the $30 I got back.
