Like most sites the owner moves away, losses interest or can no longer afford the cost to maintain site or dies. The great Jefferson City site and a couple of good sites for Lexington & Winnetonka that had all the scores disappeared before I could get info off of them. So, my Lexington & Winnetonka records only go back to the 1990s but I found another source for Jefferson City for the 1905-1949 scores I was missing.
Luckily, I had corresponded with the Webb City guy over the years and even sent him some early 1920s scores he didn't have. I have all the scores he had posted and continue adding each new season.
My collection of Missouri school's football histories keeps growing as I add more teams and still trying to find historical scores. But I tip my hat to you as I know you have more on Carl Junction than I do and maybe Lamar!
