Transient slips.
I know Ft Loudon Marina has some transient slips, but I don't think they are covered. It is the starting point of the run. Concord Marina may have some now, and in my opinion it is a much nicer marina. Those of you that did the run last year, Concord marina is the one we passed after we went under the bridge to the 3rd card stop. It is about a 15 min boat ride to the start of the run. If they can accomodate you, that is where I would stay. It is also behind where I live so I would not mind showing you guys the way. Here are some links to those marinas.
