My family and I have been on both sides of this fence. We had the honor of being named champion a few times at the Iowa State Fair and were asked to help raise funds for the auction. It has been a few (ok, more than a few!) years ago, but I certainly don't remember anyone holding a gun to our head with a minimum amount that was to be raised. Of course, the harder you work, the better the auction. However, I'm not sure that I agree that it is a big character building activity for the 4-Her. In many situations the parents play a large role in contacting local businesses that they are affiliated with to ask for the support. I agree that it can be unpleasant to makes these calls, especially if you win more than once, and it does feel a bit like begging. It is also true that many local businesses do not understand why they are being contacted and feel pressured to give money...sometimes it is quite awkward for both parties. I have several friends who have been in the same position that agree that after going through it once that they will no longer call local businesses and beg, but rather take what comes their way from other sources.
Our family supports the IFAA through scholarship money, but I do think that a better system to reward 4-Hers who exhibit champions exists. A different system may not yield auction prices of $45,000 for champion steer, but more modest (read: realistic!) sale prices may be a good idea for everyone involved.
