Hi Whirly,
Never had any problems or delays through Long Rifle area. First time I went down to San Diego I flew to San Diego International and was routed between the comerical traffic, at one point we were number 3 to a 757 and asked to expedite our approach due to following traffic - a 737!
Only thing I will say is return up the coast in day light! The cliff and mountains are hard t see in the dark - I done it - slowly with landing light on and cliff edge in view all the way to Dana Point! NOT recommended!
Fly safe.
