Shag Bark Hickory Ride

I stopped by Tim Parsons' house on the way back from Colchester. He is back riding after separating his acromioclavicular joint (same as I did years ago). He wanted to visit the scene of his crash, so we rode down to Oakledge Park. He's taking a tree-identification course and wants to decide which trees to keep on the beach in his neighborhood. Can we identify a shag bark hickory? As a matter of fact, there is one right in Oakledge. A grand old dame. We had a visit and Tim took a twig to help identify the sample back home.
