All bait should be kept cool, use a cool box and some cool blocks, the little boxes that hold six cans are ideal. Squid and fishbaits can be refrozen and reused if they have been kept cool. A large cool box in the summer ensures that your bait is cool, anything you catch and keep will stay cool and your drinks will stay cool. A good tip is to freeze plastic drinks bottles full of squash or juice and use these instead of the 'dead weight' of cool blocks, less weight to carry back too.
Do not leave the old newspaper on the beach. Take it home along with sandeel packets, tackle packets and food wrappings. Lots of people leave litter on the beach but bait wrappers and bags with the name of the local tackle shop on them are a dead giveaway that anglers are to blame, we will then be blamed for all the stuff others leave behind.
