Significance 

UNLV is located next to one of the most touristy locations on the earth- The Las Vegas Strip. Every year, millions of people travel from all around the world to see shows, gamble, and explore the vibrant night life of Sin City. While it's luster may wax dim for locals, it's still a unique spot to come admire one of man's greatest skylines- all from the comfort of campus.

This is a park and grab- but the garage requires permits or visitors passes- so be mindful of that should you choose to leave your car for an extended period of time. Full details can be found on UNLV's parking website. Fair amount of traffic and muggles, so be cautious.
