This beautiful lighthouse card was sent by Carol from Maryland, USA. She visited Assateague Island and told me about it. It is an barrier island on the coast of Maryland. It's only 60 km long and uninhabited. But there are some wild ponies there... Sounds like a mystical place to me...

A second card arrived with the lighthouse of this island! Funny postcrossing coincidence.
This one was sent by Bobby from Kentucky, USA.
