Yes, we have fireworks. I live in the southeastern part of the valley up in the foothills and we can usually see about 10-15 separate fireworks displays on both New Year's and 4th of July.
We typically do not fight the crazy crowds downtown because we have one of the highest attended shows (by locals) in our backyard at Anthem.
Something to consider, I do not know how economic downturns are going to effect the holidays this year. I would do some research before flying here and then being disappointed.
If you want fun and can stand the summer heat (Think about it, SERIOUSLY. It is 100 degreess plus AT NIGHT sometimes) come to Vegas. We've never been disappointed.
