Except for being off-the-rails creepy because of the semi-quasi implied affair between a young Brooke Shields and an old Peter Fonda, this is really a fun, feel good movie for the whole family! First, they cheat some bad guys then they get chased to and then into the Grand Canyon- beautiful but thirst inducing scenary with disappearing Native American ghosts, an apparent treasure search, and seemingly drunken script writing make this one of the movies that has been made
