This duo I spotted on my lunch break at Faneuil Hall reminds me of this collection by Alan Powdrill called "Shooting Tourists".

Oh I hope I don't look so silly when I'm wandering around snapping photos :)  Tourists really are an interesting subject...  And how about those people that take photos of absolutely everything!  Just imagine the torture their friends and family endure when they return with thousands of photos to share.  It really is kind of funny.  And the matching tracksuits?  Can't leave home without them!

P.S. Did you see Improv Everywhere's Tourist Lane? Brillant!
