A Manhattan boy, eh? We had a guy named David Maxfield who grew up in Manhattan who used to post here frequently. He probably left there 30 years ago or so. I haven't seen any posts from K-State riders (or any Kansas riders) on these fora that I can recall.
'Here is the roster of riders from Kansas' (http://www.unicycling.org/roster/index.php?state=ks) from unicycling.org, The Unicycle Page. Maybe you can find someone close by who knows more about your area. I'm a Wichita boy myself. Well, up until 1970.
