Pete L,
Book Barona and Coronado with an optional warm-up round at Maderas or Torrey Pines and call it the KP I Reunion. It will be impossible to replicate the magic of the original, but with some help, maybe a good number of the alumni could be persuaded to return. It is probably harsh to say, but the composition of the field is probably more important than the venues, and an easy location such as SD would help in this regard. The Rustic Canyon/LA and the Carmel/PB options could work, but a return to where it all began is probably best. Besides, 13+ years later, you're probably in a good place on the home brewery learning curve and are definitely the man to get this rolling.
