OK, so I'm ashamed to admit that in all our trips to Vegas (and even to Boulder City), we've never toured the Dam. This confession is usually met by gasps and head shaking by fellow Vegas travelers and I'm thinking of rectifying the situation next month. So anyway, I'm looking at the BLM website and there are two tours -- a half-hour Powerplant tour for $15 or a one-hour Dam Tour for $30. Seems like if we're going to do it, we should do the whole enchilada, but I can't really find anybody recommending one over the other. I suspect I'll be fascinated by the whole thing and my wife will tolerate it. I figure if she hates it, it's just one hour of her life she won't get back. Anybody have recommendations over one tour over the other?
