If not, you are cheating yourself out of a tremendous experience. They are not just for geezers with nothing better to do or families with younger children looking for something real on the cheap. I think they make for a perfect "Date Night" whatever your relationship--just met to 30-years married. Many medium-sized cities have them--university towns are a good source--and big cities host nonpareil shows (that's where I sneak the music mention in). One of the best times I ever had was at a traveling show featuring the Heavens set to Pink Floyd. Good speakers so you got the full aural impact. Transcendent. Here's a show but remember (1) 2-D and (2) your speakers/vision. Expand this in your mind to a full 360, all-surrounding experience and get lifted...maybe literally.
