Re: Oxford, MD
Anchoring near the strand - there a lot of moorings there, but enough room in a few areas to drop a hook. It would be a short row to the sandy beach.
I've never noticed anyone around the ferry dock monitoring how long someone ties up. There are a few slips at the ferry dock, which look fairly new.. The Robert Morris Inn now advertises free docking while dining. That might be the reason for installing the slips.
You can also anchor in Town Creek. I've seen people dinghying back and forth, but I'm not sure where they were tying up.
