Yep, Metropolitan Water District lakes (Skinner & Diamond Valley) only allow sit inside kayaks. I don't think there are any sit inside kayaks that have peddle drives. By far, sit on top kayaks are the most popular for fishing. They are much more suited to modifications for fishing (peddle drives, trolling motors, standing decks, fish finders, rod holders, etc). Maybe a good choice if you really are intent on fishing the MWD lakes would be a hybred kayak. They are sit insides that are more suitable for mounting a lot of the accessaries kayak fishermen like.
