It was pretty cool, and a surprise on the way. First thing I found was that there did not seem to be enough of them. According to the visitors center there are 28, only 27 in use at any given time as one is always down for maintenance. They also had a tibit of info on all the movies the VLA has been featured it. Most notably the movie Contact, which displayed over 131 of the radio telescopes. They used movie magic (CGI) to add them.
