Dave, how about a forum or maybe a FAQ page for mapping gardens? I keep spreadsheets on google, but I have not found a program for mapping that is easy enough. If someone could put together a step by step tutorial with screenshots, it would be so helpful. I'm trying to lay out some sort of irrigation system, and before I can do that, I need to figure out how to map all the various areas. Google maps are incredibly detailed now, so I'm using those as a starting place.
