While I've always been something of a city guy, and even my more rural-ish moments, one who's smart enough to know he doesn't know enough to freely eat what he finds growing wild, I have had a few exceptions. I'll freely tell you that meat tastes better when you've killed it yourself.
And even as an urban dweller, there are dandelions. I love dandelions. Not for their flavor, but for the fact that people are constantly hitting them with poisons, toxins, and herbicides of the sort you'd sue a company for millions of dollars if they sprayed on you, and the dandelions just laugh. But the dandelions have to be killed, to make room for the grass- a European weed that can't naturally survive here, and so it has to be fed and watered (a good thing major parts of the country aren't going through a water shortage, right?) and taken care of- and then, when that care pays off and the grass really starts growing? They cut it down. Do they eat it? No, it's inedible. Do they bale it up and sell it, like hay? No, they stick in bags and pay someone to haul it away. It's conspicuous consumption in its purest form; there's a reason I call the stuff "capitalist weed". Meanwhile, they stop just short of napalm on the dandelions, and it barely slows them down- the dandelions you can eat every last part of.
