Well if you don't do ridge flying in the Alps, I wouldn't see how to fly
there at all.

'A terrible day at Val Air today... not for me, but
Joe Dulin... a recently transplanted Turf pilot. Joe
has been flying tourists for ValAir and today stalled?spun?
in in the L-13 with a passenger on the end of the runway
after a low pass and steep pull-up.

Low passes with steep pull-ups are a blast, but as this accident
shows, entail risk. Since he was doing rides, the pilot involved was
probably highly experienced and done these many times before with no
problems.

When I was doing my motor glider transition at Livermore, the guy who
then owned the operation told me that there are certain maneuvers he
loves doing (high speed low passes among them), but doesn't do
frequently because of their danger.

One of the biggest problems with actions like low passes and tree-top
ridge flying is that you might be able to do them safely 9,999 times
out of 10,000 (or something on that order), creating a feeling of
complacency. But if you do them 1,000 times during your flying career,
you'll have roughly a 10% of an accident -- possibly fatal.

Peter Masak's recent accident that Tom Knauff wrote about in his email
newsletter sounds like it occurred during close in ridge flying. And,
when I did a Google search to try and learn more about that accident
(no luck there), what I did come up with was a 1994 post in which
Peter commented on Klaus Holighaus' fatal crash -- which also sounded
like a ridge accident.

All this is making my Livermore friend's decision sound very
reasonable. It's OK to take a chance -- but not too often.
