I trying to design a horisontal menu that sometimes will go three levels down. The thing that drive me crazy is to know if I should show all the levels.

On Apple.com, IBM.com or GE.com they usually skip the second level. And from a design point of view it looks good but unless there isn't a breadcrumb menu somewhere there is no way to know where you are in the structure.
How do you generally deal with the connection between global and local navigation?
