The facet I like most about Charlie Radoslovich's Rad Urban Farmers business model is that he is a farmer without any land. From the top, you know he's either a wacko or on to something significant. I'm thinking it's the latter.
He told me he didn't devise the ideas, but he's certainly on the front edge of the wave. If he's successful, think how much land under lawn-grass cultivation could be converted to productive use.
