First of all, it's important to note that Dumpster diving does not actually entail climbing inside and rummaging around one of those giant metal bins. It's more like yard-sale shopping, except nobody has taken the time to set up poster-board signs and sit outside collecting quarters for old flannels and ashtrays. Some call it alley-shopping, since essentially what you're doing is surveying curb trash for treasures. Whatever you call it, here's the skinny: Go to Tanglewood. After all, it only makes sense that Houston's richest neighborhood will turn up the best finds.
