Thinking Auction

It is getting to be auction time at the kids school and now is when I think about what to donate. Two years ago we donated a Low Country Boil at our home, which was so popular that we did two dinners. Last year we had a Kentucky Derby Party. So what do I do this year? I loved doing the Derby party, but will it seen lame if I do it twice? I thought about doing a Sunday Dinner, you know... baked chicken, mashed potatoes and gravy, green vegetable, chocolate cake. It wouldn't be a special thing for my husband, but for some people gravy is not a common occurrence. I am already donating a Fancy Nancy party for 10 little girls, for which I have been stock piling all kinds of goodies. Any ideas? What kinds of things are donated to your school's auction? Any corporate connections that you can pass this way?
