I am sure there will be better advice from those that currently live in Cali, but San Diego has some great shore diving. I lived there for 6 years when I was in the Navy. It seems though that most of the members are from central Cali, so maybe up by Monteray Bay might be more convienient. I would be willing to do something in the Ohio-Michigan area if members can`t get down to Florida for the day dive. As for the trip in July, just pick a place! They will come!
