When you 13 year old happily spends the entire week of spring break building a huge, elaborate diorama of the Greek underworld using Peeps for the local newspaper Peeps contest.

And books... my parents could not understand when we went skiing with them annually in Colorado why my kids loved the day best when we skipped skiing, went to a great bookstore nearby, and then went for ice cream with our bags of new books. It was WAY cheaper than a day of skiing to buy them a bunch of books, and my kids liked it better.
