Mark, I haven't played Soule Park since my college days in Santa Barbara 40 years ago, but do remember it as on nice rolling terrain, don't remember much else. Ojai, which is nearby, is on some gentle terrain with steep hills and barrancas in the area which was the beginning of the back nine but will be the front nine apparently. Bell assisted George Thomas with the construction of Ojai.
Thomas also designed La Cumbre in Santa Barbara but I don't see much similarity to either Soule Park or Ojai. I don't think either has the kikuyu which is choking La Cumbre these days.
There was some talk a while back about possibly playing Soule Park as part of the King's Putter GCA unoffical event in the spring.
