One mans photo essay;

One of the great Chicago traditions is “dibs”.

Dibs occurs after a resident shovels snow out a parking space and then places a household item in the spot in order to insure their parking place is still there when they return.

I have seen spaces reserved with ironing boards, lamps, tables, buckets and cones.

Today, I decided to concentrate on the chairs that people put out by the curb.

In an hour of driving around the streets in Chicago’s Pilsen neighborhood, I photographed well over 50 different types of chairs.

Here are 49 of them.

Well, actually 48 chairs and one tree trunk.

I think it’s bagsies in the northern part of Britain anyway. Was in Glasgow when I was growing up.

“Dibs” is universal. It was in place when I was a schoolchild in California, and I am now 68 years young.

It was bagsies in the wilds of west London when I was growing up, too.

Bagsie in North London too

Dibs and bagsies here in North Wilts, but possibly in slightly different contexts, we’d say ‘bagsie that!’, if there was a bunch of items, or ‘can I have first dibs?’, if something was in the offing.
Similar meanings, though, I guess.
People here would obviously go and dump their wheely bin out front… 😉

Translated into German ‘Dibs’ = Tuch

Bagsie in the FoD

Baggsy

(in Sweden too, though they can’t spell either)
