Taking a picture of or in front of the sign is a must.
It's in kind of a busy area and hard to stop but worth it.
There is also a sign at the beginning of the old Vegas strip that is worth stopping at.
It's iconic and gets you giddy and exited, because you know right there is where your adventure is about to start, there is no trip to Vegas without something crazy happening
Las Vegas is Fabulous, just like the sign says.
