Pic of leaves
Could be Black gum, Nyssa sylvatica.
Thanks Esh and Jeanne! They *look* more like the tupelo/black gum but they are very young. No acorns so I don't think they're oaks though maybe young trees don't produce acorns? Going to keep an eye out for flowers and berries next yr.
Jeanne: I tried to put all pics in one post but I didn't realize that if you edit your post before posting (preview) you have to re-enter the pic to be uploaded before you post your message...I've got it now :) Sorry for confusion!
