PTO Today

I need ideas and help on planning a small, yet successful fall festival for a high school fundraiser. Our school is somewhat new (11th grade will be the highest grade---we add a grade each year) with needless to say a very, very ,very small budget. I've seen plenty of elementary fesitivals ideas but I need something that not only will attract the younger kids, but older ones & adults as well. So far, my ideas include: Cake Walk, Face Painting, Fish Pond, Dunkin Booth, Coin or Ring toss. Can someone give me some more ideas? Thank you in advance.
