i didn't know until you mentioned it that there were two conewago creeks i'm not sure for that matter that i distinguished between conewago and conewingo creek i drive my wife crazy by jokingly talking about the community of lil' tits and the coca lico creek i have lived here less than a decade but i know more about the area than my wife who's lived here for a quarter century so i'd say that while most people don't distinguish between the two people that live in the vicinity of one or the other might i noted the discussion over chiques chickies chickie's and i can tell you that the local news media consistantly refers to it as chickie's i'd use chickie's over chiques it's possible for the usgs to make mistakes but it's your bat and your ball and for my money you can call it whatever you want to how about an article called conewago creek that discusses both creeks just as the turkey hill article discusses both turkey hill minit markets and the turkey hill dairy which are separate companies it blew my mind when i first ran across the turkey hill article but it actually works out well since your two creeks are so near each other that approach might work out well for you too or not as i say your choice help make wikipedia the most authoritative source of information in the world
