Nick Kristoff makes lots of good points about the importance of experiencing nature but he's clearly not a gardener. We know this because he writes about nature as something you visit on a yearly backpacking trip. Here's his column in today's NY Times, and there's a link at the bottom to comment about it on his blog. I did, in a potentially embarrassing bout of gushiness over gardening.
