Do not waste your time by driving to Harrah's Cherokee. This place is a total sewer, and the worst excuse for a casino I've ever seen. It is rife with slot machines and chain smokers. Yes, they have "live" blackjack, but only the dealers are live, the game is a video version of blackjack, and the system automatically shuffles at the 50% point. Nobody can beat this game. Your best bet if near this place is to continue over the Smokies to Gatlinburg, or visit Cade's Cove.
You should join Green Chip, cheapest place to interface with players who have "been there" and will provide you a wealth of information that is non-existent in any book you can buy. Additionally, you will have access to the Archives, which will also provide you with a plethora of good stuff. Many GC members will assist you with answers to even the most basic of questions you might have.
Above all, BELIEVE THIS...you will get your ass handed to you from time to time in a casino, be prepared for this, it happens to all of us. You will not be exempt from this experience, it's part of the game. It ain't fun and you won't like it, but the pain passes quickly. You will know when this is happening, no matter what you do, you will get stiff after stiff, or bust after bust. Take a break, take a walk, get some fresh air...don't just sit there and have the casino hammer you.
