I agree with others on Cottonwood , could be Black Walnut but it likes to grow crooked by looking at the ones we have
Turns out to be a Walnut tree. I went back there yesterday to do more work and asked the lady. She told me. I did a real quick look for leaves and nuts but nothing. I was going with cottonwood myself.
Mystree solved. Have a job to do for the same customer and found golf ball sized nuts in the driveway and on the tree. Its a walnut! Multi family house and the guy tells me the cars get dinged quite often. Luckily im not working under it! A couple others in the yard. Told the guy it was highly valuable! EDIT! i didnt realize the mystery had already been solved! Read #24 above!
