A challenging round-trip to Orange County, California." Celine invited us several times to visit her in Pittsburgh but my husband's illness was too advanced for a trip, then last winter, it was too cold to fly north ... About a month ago she tempted me to come by sending me a link to the Pittsburgh's Frick Museum that is having an exhibit on 1940s photographs of Paris. The flight only took about 1 1/2 hour. I had thought of Pittsburgh as a northeastern city, flat, grey with many factories. As the aircraft circled the downtown center I was surprised to see an interesting group of buildings, rivers, bridges and hills.
