Tree at Oakwood with compound leaves

I saw this tree at Oakwood Cemetery. Alternate compound leaves. Alternate compound leaves could be hickory, except these seem to have three leaflets, and hickories seem to have more than three. I didn't spend much time studying this tree. Did it really have three leaflets? Hoptree has three leaflets, but hoptree is short. I'll have to go back and observe more carefully.

Ash and locust

Last Monday, my neighborhood was yellow with ash and locust.  Today, it's still yellow with locust.  Some of the ash trees are mostly bare, while some still have many leaves.  It seems like the older, larger ones are more likely to still have leaves.
