Spotting the Tourists in the Crowd

Can you tell the locals from the tourists in this image? Before Blogger and Facebook, I was active on Virtual Tourist,  they have a very active online forum where people can post questions about travel and get advice from other forum members.  Every week someone would post about planning a trip to a foreign land and wanting to dress like a local so they would not stand out from the crowd as a tourist.  I frequently responded, dress comfortably, and modestly and don't try to look like a local.  The locals can pick out the tourists.  We look different, we dress differently in subtle and sometimes not quite so subtle ways. We talk differently, we carry ourselves differently.   I notice differences in foot wear and socks as I travel.  In Europe, printed T-shirt in English featuring "American" themes, frequently are fictional to avoid paying licensing fees to US universities and athletic teams.
