Matt, my first impression was a sweet cherry that we have here around Appalachia but the leaves looked different to me. Sweet cherry has been cultivated in your area but I'm sure the serrations and veins don't match, but close, so I looked in one of my forestry books and I'm somewhat confident you have a sour cherry there. While not native, they were cultivated in your area, especially alongside roads and the drawing in the book looked very similar. If it's not a cherry of some sort it may be in the plum family. They can look similar. Ohio Matt
