Mark DOES look west-coastish, with good reason. If he traveled much farther west, he'd be in salt water.
A distinguished looking fellow, fer sure.
This sounds familiar to me...my daughter once had a job at a trendy chain clothing store called "The Buckle", and the manager (a chubby nightmare stuffed into pink sweaters too small) once said her style didn't match the store, telling her she was "west coast casual". This - from a lady who dressed like a fuzzy pink sausage...to my slender daughter who was 5'8", weighed about 135 pounds, and has always had a nice sense of dress.
We have been laughing about this and trying to figure out what it meant for years.
