Engineering Site Seeing Web Site

During National Engineer's week this year I saw a link to a web site that provides a list and links to sites with engineering significance (A Sightseer's Guide to Engineering).  The site is very handy when planning a vacation to identify cool museums, historical sites, or just general sites of engineering significance.  The site is definitely missing many significant sites, but it is a start, and it is very well organized.  I hope they keep building on this and increasing the size of the database.  For example, the EAA Musuem in Oshkosh is missing from their list of engineering sites in Wisconsin, which is a huge oversight!
