I can't say that Reno holds any events that I like to go to. The Genoa Candy dance is my favorite. I also like Burning man because it frees us from the hippies for a week and if everyone wants to free us indefinitely at least they are all in one spot!
The rib cook-off is by far my favorite. I can't find decent ribs in this town any other time, and I love them hot. We live about a mile and a half from the square and will walk down there every day, eat some BBQ, and walk back. Fortunately, the weather has been relatively cool on those days the past couple of years. Before that, we did a table, but they don't bring any of the hot BBQ sauces into the tables area and I had to run out and collect sauces on the sly. I won't do that again.
