Indeed, Saticoy Regional was the original Saticoy CC, designed by George C. Thomas. As for the Thomas design it is long gone.
The current Saticoy CC, designed I believe by William F. Bell, is an over rated course; over rated because it is very difficult and thus some (no one here of course!) think it is a good course. Actually if one removed all but 10 trees on each hole, the course has some hope.
