Always have to pay for parking.Check the tide charts, you need to go when the tide is low, places with rock jetties, and when you don't have to pay lol
ThanksWalk out to the rocks and grab hands full of sea lettuce and mussels attached to the rocks and put into your bucket. You will see thousands of pods when you rip out the clumps. Probably catch little crabs too which are also in my sump. Once you have enough put something in bucket like a piece of cardboard they will gravitate to the cardboard. Then you just put cardboard in another bucket with saltwater and shake them off. You can also use a net to catch the swimmers.
