My favorite way to get back to where I want to be is to be left alone while I watch trees blow in the wind (with or without some soft music and a fresh cup of black dark roast french press coffee). My wife recently started a garden and a day or two ago I went to water it and I got almost as lost in holding the hose and tending to it as I do watching branches sway, so I totally get what you mean. We're hoping to get a house in the next couple of years and there will totally be some sort of greenhouse on our property. Green thumbs unite!
