Really, the Museum of Science and Industry has got to be the all time bigest waste of time/money/effort/space I’ve ever come across. A friend who was in town suggested we check out the Body Worlds exhibit. Sounded great! I still haven’t seen it although I did catch the slightly less artistic Chinese knockoff a few months back when I still resided in the Bay Area. We had almost 4 hours to kill before the run to the airport, and of that time we spent all but 1.5 hours in a line. lines to get in, lines for exhibits, lines for exhibits when you get tired of waiting in the other lines and you bail out for something else, lines for the bathroom etc.(really it goes on and on) This was my 
favorite part of what I did see, from the science of yester-year.
