What ever happened to just cake and ice cream?

Ryan and Zachary are turning 2 on Monday. We're having their birthday party over the weekend. I decided to "keep it small" this year, but that still means about 15 adults and 7 kids. We are going to a nearby park where we will be able to go on a train ride and let the kids go on a pony ride. In thinking back to birthday parties I had as a kid, I don't remember things ever being so extravagant. Which brings me back to my topic, what ever happened to just cake and ice cream? If you want to share any of your birthday planning experiences, please post. We'd love to hear your stories!
