Yes the oak tree is a scarlet oak as far as I could tell. It seemed pretty clear when looking at it in person. The maple could possibly be a cross with fremanii, but I would not know what to look for to distinguish it from a simple red maple. Elswhere on the tree the bark and leaves looked like pretty standard red maple and I think that is the best ID for the tree.
"I love science and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awe by nature. Science is not meant to cure us of mystery, but to reinvent and revigorate it." by Robert M. Sapolsky
