After living in Vegas for a short time, I've made it. No, I didn't become the headliner for a show on the strip. I made it to a baseball game.
I attended the 51s game for a Yelp CMYE outing, and I couldn't be happier with the experience.
I didn't know any of the players, or anything about the teams. I just wanted to come out and hang out with my yelp friends, and have a good time. Having said all that, I do watch baseball, but just not at the AAA level.
The game atmosphere is nice. Concessions are cheapish. Bathrooms are clean, and I had one hell of a time with my friends.
My advice to you? Try to pay attention to the ball as it is being batted. You don't want to be THAT GUY who gets beaned in the head because he wasnt paying attention.
