The other evening, after parking the car, I stepped onto the sidewalk outside our apartment and almost collided with a young woman.  My fault, not hers.  She was walking a straight line and had right of way.  Going at a steady pace, with barely half-glances up and without a misstep, she was reading a yellowing mass market paperback (what we always used to call pocket books) copy of Robert Heinlein's The Door Into Summer.  It struck me as so appropriate, since it must still have been 93 degrees at 7pm, besides having been that or higher for most days since April.

What a cool thing to do on a warm evening.  Happy Summer Reading!
