Let me add a little more about Pekin, for years their sports programs were built around farm kids that had played for Coach Stone, and they wanted to have their kids play for him like they had. The program was beginning to slip in the early to mid 90s, but then merged with Hedrick school district. Hedrick did not have much for numbers but they had very good athletes, you add 3 or 4 good athletes into each class into an already successful program, you are going to continue to win.
Like most of Iowa, where there were a lot of small family farms, many have been bought out and the kids have moved on to better jobs and opportunities that are just not available in rural areas. They are winning this year in football, but they have struggle the past 3 or 4 years. I was also told that they are now getting fewer "good" kids from farm families and more kids that just do not have as good as work ethic as those before them had.
