[cctalk] Slightly off topic --Places to go in Huntsville

Next week I will be in the Huntsville, Al, USA area for an entire day with no commitments. Does anyone have recommendations on how to spend my day? I have been to the space and rocket museum several times. Any computer museums or displays, especially of space-related equipment? Any good surplus stores? All suggestions welcome. Thanks, Will You don't understand anything until you learn it more than one way. Marvin Minsky
