Thanks CSX - actually, the new issue of Nuts and Volts just came today. So, I've got that to read as well as the new CTT mag. Working on a science fair project with my son, too. I think we have just a couple weeks left and of course we have not yet started. Nice pics, Jeffrey - looks like you were having some fun today. David, is that a Bachmann Goose? Prayers for no snow, John!
