My mind is now at peace, Cookietown once had cookies.
Apparently, Cookietown used to have a general store, circa 1928, (and that was it) and the proprietor, Marvin Cornelius, would give out cookies to kids (so the legend goes). One kid didn't want to leave "Cookietown" and thus the name was established.
This general store is still supposed to be recognizable (now whether that means that there's a building, a foundation, or a cobblestone to mark the spot- I don't know). I guess this gives me an excuse to pack a few cookies and head out to Cookietown again.
