Stopped for a little site seeing between the Grand Canyon and Las Vegas so figured why not check it out? You do have to pay for parking and then if you want inside the building that's there you have to pay and if you want a tour you have to pay, so we just walked around, did our own thing and snapped a few photos because we didn't feel like getting ripped off. But it is a historical site so good to see once. Don't get your hopes up though, it's literally just a big Dam .
