I used to live in Vegas, it's Pride is no big deal, actually Portland, Oregon or Seattle, Washington Pride festivals are SO much better. Folsom Street Fair is okay if you are into Straight Fetishes, but not so much for us Gay Men, for the Gay version of Folsom, go in July for Dore Alley!
Southern Decadence is BY FAR the Number 1 choice for Gay Events in September. The Booze is flowing in the Bars and on the Streets (All bars serve drinks in plastic To Go Cups, and many bars have "Walk-Up To Go Windows"). The New Orleans Bears Club (NOBBTSC) also hosts Bear Decadence at the same time and you can register for 5 days of events (Including Drinks and several Meals) for less than $100. The Gay and Bear owned B&Bs are all within walking distance of all the events and much cheaper than ANY hotel because they don't charge Hotel Taxes (This year, I only paid $345 for my Room from August 31 to September 7). Decadence includes Contests open to all participants no matter where your from (Sire Ursus, Decadent Cub, Best Hairy Beard, Belly, Chest & Butt, etc.). There are Pool Parties every day, several block parties, Beer & Liquor Bust every day, Bar-B-Ques, Parades, Tours, All night Dance Parties, and at least two Bars (The Infamous "Rawhide" and The Eagle) that don't even allow Women or Drag Queens in them ... No Matter What!!!! Most of the Pool Tables are occupied by Balls that don't have Numbers on them and Sticks that you would use Lube on instead of Chalk. Decadent? Yeah! Hence the Name! There is deffinately something for everyone, Twinks, Models, Porn Stars, Bears, Leathermen and Cowboys are everywhere you look and are all very nice and hospitable, unlike the Snobbish SF and Vegas Crowds. I have made Lifelong friends at Southern Decadence and refuse to miss out on my Favorite Event of the year. This will be our 5th year in a row, including the year of Hurricane Gustav!
