Now that me smile Brian. Not only a nice image and a quirky subject but the phrase 'pistols at dawn' sprang into my head. Now I have a vision that this is a picture taken just before some sort of combative event. Maybe one guy cut another up with his stroller at the mall and it needs to be sorted out. Pram to pram!!
Pete and Paul,...What imaginations you chaps have! LOL. I admit, though, that the prams were a bit of a surprise to me up there that night. There may have been something more to it; I never saw any bairns after all.
Their wives were indeed off to one side egging them on Pete, but in Spanish. Given your (practically clairvoyant) ability to divine accurate meaning and detail from the most obscure images or inferences, I am sure that's what it was!
