What I've found is that the best place in San Diego to catch a lunker trout from your kayak is at Lake Cuyamaca, or Lake Jennings as mentioned before.
Again you run into $20 in fuel to get there, plus time, etc.
Once upon a time before I owned a kayak, I used to go to Santee Lakes. I got my name in the newspaper for this guy. 25.5" long and just over 7 pounds.
