Racer, you certain can attend the “Expo” portion of the Arnold Classic without paying for and going to the bodybuilding shows themselves. Go to www.arnoldclassic.com for details.
The expo is held in the giant convention center downtown, attached to the Hyatt. Door entrance fees are usually about $10 per day, but you'll make that back in ten minutes with free samples. In the expo you'll also eventually come across a big stage area, where world class powerlifting events are held (with Louie Simmons, Anthony Clark, many others), and sometimes other events. They always have entertainment, strongman exhibitions, etc.
The contest itself is held at the old location, across the river. Believe me, you’ll find enough to do and see in the Expo to occupy you for as many days as you are there. For the greatest “free sample” boost, be there when the doors open Friday or Saturday (probably 10:00 a.m.).
See you there!
