I like how she is "just doing it". As described, it's not primarily part of or subservient to some "agenda". Seems rather "hackerish"; hacking the local setting to combine urban and rural elements in a mix that suits her.

My one caveat would be to make sure your soil is safe; urban settings have trouble with contamination, from "brown fields" to lead paint, motor oil, etc. The problems can be remediated or worked around; the thing is to know about them so that you can do so.

I think the HN crowd is more likely to understand this safety issue. My challenge when talking with friends who start urban gardening is to point the concern out without sounding negative about their project. I'm really just concerned for their health; as long as that is assured, more power to them. Unfortunately, I think sometimes my attempt to be helpful in this regard just comes across as negative.
