I've been up here in Vegas since November 2014 and I visit the Fremont Street Experience every third week or so.
The people-watching is great. Every now and then there's a good concert on Saturday night. And the guy with the saxophone, in front of Binion's, puts on a great show most nights.
The downside: the kiosk personnel will sometimes get in your face and insist that you buy something before allowing you to pass. The panhandlers are getting much the same way....I've already been followed inside of a casino by one of them.
There are security personnel, but they are conveniently nowhere to be seen when these types of incidents emerge, which unfortunately, is starting to happen on a more frequent basis.
