My response regarding the kid part of your post is read your title -- "They are just kids." I actually like seeing neighbor kids playing outside -- riding their bikes and scooters and playing games. The sounds of summer generally make me happy. I love the sounds of music playing and people and kids at a swimming pool. It actually makes me sleepy. It reminds me of childhood.

Occasionally when I want to take a nap it is a tad bit annoying but I remind myself they are just kids. I actually bought the girls next door a few boxes of sidewalk chalk last week, and they and a few other kids covered my driveway with their drawings and made me a thank you card out of pressed flowers. The boys on the street can get a little noisy when playing basketball but I just move to another room so I do not have to hear the thunk of the ball.

As far as the drunken campers and teens, I would call the police if it is too much.

It seems to me that if you live close to a recreation area you going to have to expect a certain amount of noise, music, traffic, etc.
