Yep. New Carlisle is right inside the St. Joseph country line and "might" be considered part of the Chicago DMA, but I'm not sure since it's only 12-15 miles from South Bend.
New Carlisle is Eastern time, but their High School is across the county line so the whole school system is on Central time, even though the one primary school is in Eastern.
The zip is 46552. See if that works for you.
D'oh! I just remembered, we get Comcast Chicago in South Bend, so you should come here and check out the Studebaker museum while you're watching the Cubs/White Sox/Bulls/Blackhawks/Fire.
