If you can post good quality images of the bark and leaf arrangement to
ABPG, I'm sure we can nail the ID. I agree that the characteristics you've
shared so far are along the lines of white ash, especially the diamond
pattern to the bark. Look around on the ground for examples of the fruit--
if it's ash there will be samaras that look like canoe paddles, 1-2" long
and about one-quarter inch wide.

Dirr describes the leaves of Boxelder (Acer negundo) thus:

"Opposite, pinnately compound, 3 to 5 (7 to 9) leaflets, ovate or
lance-oblong, 2 to 4" long, coarsely serrate or terminal one lobed,
bright
green above, glabrous, lighter green beneath and slightly pubescent or
eventually glabrous; petiole---2 to 3" long."

So I doubt it's Boxelder.

I think it might be a white ash. I looked up some pictures online and
the 3-leaf arrangement looks very familiar, albeit the leaves on these
trees look "whispier", much thinner than the picture of ash leaves
online. The bark is also a gray color, and makes occasional
"diamonds" while going up the tree. These trees are tall, some are
taller than the resident oaks, but most are about average to all the
other trees.
