Thanks for all the input.

If I could see the "V" between the lobes better I would know for sure. If it comes to a sharp point there it is a red.
Russell,
I already threw away the leaves, but I zoomed in on the original pic on my computer, and I couldn't tell for sure, either, whether it is a sharp point or not.
Maybe I'll find another leaf.

Around here all we have is Red's and some of the trees have 5 lobes and some only have 3 lobes but they all have teeth or serrations.
What I found is that when it comes to mother nature everything doesn't always fit exactly.
Dennis,
I think you may have hit on it. I wonder if they are both reds after all...

Harder,
I wondered, too, if the bottom left wasn't a mountain maple, if not a red.
