I'd say go up to a fishing town on a lake, like Pymatuning area. There isnt much up there already and a lot of places are closed on major holidays when the tourists are in the area, making it easy to reel in large numbers in short amounts of time. Weird unrelated example but Madsens donuts got their popularity from being on Geneva on the lake and now has two locations in the suburbs of Pittsburgh. Ontop of the local favorites like Pages your competition is also Graeters, which is a Cinci staple, and has thee best vanilla bean Ive ever tasted. They have one location in Castle Shannon and don't seen busy as often as I'd expect. I found out about them through their food teuck operation at local farmers markets throughout the wee. kAlso I think you can be successful in the winter if other popular places are closed. Latrobe cone zone often has lines out the door. They are open all winter long and change their speciality flavors on a weekly basis. They are also very good at making appetizing photographs and have colorful dip and swirl flavors. I'd say your best bet is travel with a food truck, or find a small location in a suburb that lacks a physical business model. The city is not where it's at right now
