I've been receiving many map card from USA as officials last weeks and I'm really happy about it :) This one shows the Whidbey Island in the Washington state. By the way, I used to think that Washington state was probably somewhere close to Washington city... But Postcrossing is very helpful, when it comes to treating geographic ignorance ;)
Whidbey Island is the longest island in the United States. It was discovered in 1792 by Captain George Vancouver and named after Joseph Whidbe, a member of his party, who found Deception Pass.
