In your opinion, which place is more fun, Las Vegas or Reno?

depends what you're looking for. LV might be construed as "more exciting" so if that's what you want, go to LV. If your tastes run to things a little more peaceful, head to Reno and be sure to drive over to Lake Tahoe, which has several major casinos on its South Shore, PLUS the beauty of the Lake and tons of nature-type things to do. The huge forest fire actually happened in Meyers which is further south of the "tourist" area.
