As for Vegas:
I assume the vast majority of people reading this are pharmacists or in pharmacy school. You know how to party. (If you don't party for personal or religious grounds, you are respected and please take no insult).
Where is THE destination for people who like to party? New Orleans for one day/few short weeks a year? Brazil with one of the highest per capita murder rates in the world?
Sunny Las Vegas, Nevada, with a party ~365.25 days a year
