Lake Mead for the "Riverboat tour". Near the Lake Mead Marina at Heminway Wash is the "Desert Queen" pseudo river boat tours. A very well done imitation riverboat takes regular tours out into the lake around the point and near the front of Hoover Dam. Every 'out of towner' I have taken on this tour has enjoyed it totally. An evening dinner tour is also available. .......... NevSmith
