I received today an email at my office from Dassault Systems (makers of Solid Works) advertising their new free 2D CAD package. I downloaded and installed a copy. For lack of a better description, this is an AutoCAD clone. I have not done any extensive testing yet, but preliminary poking around revealed commands I would not have thought to be the same, are.
Anyone interested in a moderately advanced, yet easy to learn drafting package should give this package a try. If nothing else, it will take the guess work out of laying out a track plan in the garden.
Edit: It would help if I included the URL http://www.3ds.com/products/draftsight#vid1
