autoflt,
Only been there twice and had no sheer problems. The main caution to our ops was to keep speed and sink rates under control to avoid GPWS warnings due to the varying terrain.
Arrivals were in early AM and the sun off the top of the fog/haze was the main worry as the very thin layer was virtually invisible from the ground.
Great place if expensive to spend a day or so. The memorials and scenery are quite stunning.
