Tryon Creek park is huge with many trails but maybe not so many where bikes are welcome. Today I thought I'd explore mixed use horse trails but couldn't get to the park do to bridge construction at Arnold.

On my return home I revisited Marshall Park, took a few more pictures, and then had a mechanical breakdown requiring rescue.

Arnold Creek meets Tryon Creek which continues under the bridge construction to the right.
