Stroll around this little museum in the Boulder Dam hotel to kill an hour and learn about Boulder City's beginnings. It's concise and informative and costs peanuts to get in. If you're local, you get in for free. The art gallery is cool - only artists within a 50 mile radius so it's truly local. It's a cooperative so the artists have to work in the gallery which equates to lower prices for the customer. There's done really great water colors.
