Again, if we are calling this Fireman's Landing, there should be a boat aspect to the area. I know it would take license with Ozarks history, but some sort of fire boat sitting in the lake, with fountains spraying from it might be an interesting addition. I don't know that it needs to be a ride, but it could be a cool fountain feature. Maybe it could even do a dancing fountain show at set times throughout the day. Light it up at night for a light and water show.
With enough viewing area, something like this could create a "mist-curtain" for a nightly projection presentation of the Bald Knobber history and tie the firefighter theme to FitH.
