Be careful riding back into shore. Waves over 4' can hide the person riding them. Tom almost got hurt one year because he was riding a wave, was at the base of the wave, and someone came over the back side of the wave. They hit the ski instead of him. Riding back to shore is not a race.
x2 on the beach carts. Throw in a hand pushing a cart up the beach if you see someone doing it by themselves. Pulling a cart by yourself is murder. A second hand pushing makes life easier.
If you don't own a beach cart, don't just grab one off the beach. Someone broke down last year and took my cart. They returned it but it was almost 30 min later. I was understanding and didn't get mad, but I was frustrated. Someone took my cart with out asking so I had to go borrow a beach cart. Ask someone at the beginning of the day if you can use their cart, and if they say yes, always return it to the exact spot you found it. People are not entitled to another person's beach cart. If that's a problem, bring your own.
As someone said about not taking someone's wave, true, but at the same time, don't hog them. It can get super busy and if you are not getting enough waves, and you can't skip every other one, go to a less busy area.
