My only experience dumpster diving occurred the day I tossed my newspaper -- and my car keys -- into a recycling dumpster.

Not one of my fonder moments.
That said, I'm very tempted to go out and dumpser dive right this minute. We have community trash collection with dumpsters, and I just tossed my garbage and noticed that someone has thrown out half a dozen commercial totes. For those who don't know, these are stout, reusable packing cases with hinged lids. They cost a bundle, and I'm outraged by the sheer waste. Those things are built to last for years.
Doubt that I'll risk climbing into a dumpster for them, but I'm so tempted.
It's shameful what I see casually tossed because people are too lazy or too negligent to donate. Goodwill and the Salvation Army even advertise free pickup. Shameful!
End of rant.
