The Fremont Street Experience might be a lot of things, but you must check it out anyway. In the heart of downtown Las Vegas is a fully lit street with a canopy of lights that goes off every hour with a musical show that is fun for all ages. Personally, I like it. However, I also like the largest ball of twine and other weird stuff. I wouldn't go out of my way to see the show every time I visit Vegas, but if I am there to catch it...bonus!
The last show I saw was KISS. I posted a video of it on my YouTube account. It was worth watching for sure. There are a wide variety of shows, and they change them/add new ones all the time. 4 stars for being one-of-a-kind.
