An exhibit opened Friday at the Clark County Museum in Henderson focusing on casinos that have disappeared. It sounds like it could be pretty good.

The museum is way out on Boulder Highway, not very convenient for most tourists. But if you have a rental car during the convention, it might be worth a side trip. I'm going to check it out today.
