Then Lyndbergh is perfect..you can actually walk to the airport..really...
From downtown Charlotte to the airport is at least 15 20 minutes, a few traffic lights, and a lot of weirleft hand wheel cars driving on the left side of the road..
You're perfect at Lyndbergh.
I am sure you can moor there, I have seen many many boats stay there, some weeks in a row.
Bellow is a shot of Lyndbergh bay...see the airport??
