Educated guess would say Route 30, but did you go through on Old Route 30?
My mom's from Warsaw, but lived on the outskirts of town. When the corn wasn't up, you could see my grandma's house from Route 30.
That is one cute little boy, and your wife looks great for the day after giving birth.
Slight addendum from above: When the corn was up at my grandma's house, it was quite eerie how the corn would muffle the sound of cars coming. You wouldn't hear a thing until the car got past the field, and it was once again silent when it cleared the yard.
