We saw the most interesting memorial in San Diego. It's called the National Salute to Bob Hope and the Military, and it's really striking. It features life-size statues of Hope surrounded by U.S. service personnel (from various parts of the 20th century, from WWII to the first Persian Gulf war). While you look at the statues, you hear one joke after another as Hope entertained different generations of personnel ... often making quips that showed enormous empathy for the conditions they were in.
If you ever go to San Diego, take the time to have a look. It's remarkable. You'll find it near the U.S.S. Midway, the former aircraft carrier that is now a floating museum, and near a series of monuments honouring "The Greatest Generation."
Here's a slideshow of pictures I took.
