These photos come from my recent trip to Pittsburgh, Pennsylvania, to attend the Mathematical Association of America's summer conference: Mathfest. Above is a view from the car, as we drove south.
A light in the very ritzy William Penn Hotel, where the conference was held.
Signs at the, uh, strip mall next door to our hotel. What a strange combination...
Rusty corners at a service plaza on I-80.
Giant rolls of shredded wheat! ... or, harvested straw in a field near my parents house, on our way back north.
