Are there places in Vegas my friends and I can get away with? (We're 19)?

One thing you will learn being in Vegas is to have your ID handy at all times. You will not believe how many times you will have to show it. If you register for a gambling club you have to produce your ID. To get discounts on some things you will have to show your ID. To do all the things you think you can get away with ... you have to show your ID. They take the age factor very seriously here especially now since a few clubs have been busted allowing underage kids in. They found it is not worth the risk anymore as the fine was half a million dollars.
