Rangers to not enforce the park rules!

wonderful park! Only problem is the park does not enforce their rules. Several sites had 3 to 4 cars/ trucks and as many as 15 people per site. And these were not the double sites which allow greater numbers. This was observered on single sites. Rules say max of 6 people and 2 cars. This creates very loud partying late at night. I asked at the ranger station about the rules and discussed what I saw what I experienced. Pretty much just blew me off! Reserving only one site and packing as many people as they can get away with does not create a very family friendly camping experience.  Only leads to trouble.  No Rangers in the Park after 8pm which to me is a safety issue!  After 8pm the local police in Dodgeville take over.  We were there 5 nights and only saw the police roll through 1 night!  Too bad.  Such a nice Park is going down hill!
