I like having my 85-pound gushing mush labrador on a 100ft lead so he is certain to make it over to the next few sites near me. He gets to say "hello" to everyone, knock stuff over with his tail and lick all the plates on the picnic tables.
Then we set up Corn Hole from the far edge of our site to the other, drink beer and whip the bags far and wide, making sure they end up in the lap of other campers resting on their outdoor chairs.
Finally, we make sure our clothesline is attached to a tree inside our neighbors' site and let all our wet swimsuits and towels make a great colorful mural for them to see.
