So all of Marc's buddies at LST have been wondering what he looks like -- so he asked me to post a picture! The pic below is my favorite -- only marred by the fact that he wasn't smiling.
He usually wears a red T-shirt (though sometimes blue, and sometimes gray), usually with "USA" or a flag, or something similar.
Here is another pic that shows him in a more natural state -- he has a wonderful smile (a little shaggy tho on this one)! Both pictures are from our birding trips... and yes the hat, though appropriately red -- is not "made in the USA".
