That plaid takes me back to the NYC public buses on Staten Island, and the girls who would hop on for a few stops. Back in 5th-7th grades or so. With the wonderful bus pass, you could get into the transit system all day long for a nickel. Early 1970s.
Maybe after a certain time, the uniforms were no longer so obvious, or the girls found other means of transportation.
Forty-five minutes on the bus (this is exactly what they looked like),
then about a three-quarter-mile walk through city streets (caveat emptor: this is Park Slope, but it could pass for parts of Bay Ridge; I'm lazy)
and then duck ponds and past one mean-ass rooster. In Brooklyn. (Yes, this photo is of the school I attended from 1969 to 1977. Not a thing has changed, except that little structure off to the left wasn't there.)
UPDATE: In a weird bit of synchronicity, and there's been a lot lately, one of the boldfaced folks in my Brushes with Fame took the 2010 photo of my school's duck pond.
