Big bonfire - picnic table loaded with finger foods or pizza - coolers loaded with various sodas, water - music coming from house, cars, d.j. - any friends that play instruments (guitars, etc.) bring to play and just see what happens. You'll have friends singing and makin' memories!!!! Make sure there's all kinds of chairs everywhere, and trash cans too. Keep adding whatever you can think of. My son and his friends loved it!!
