I worked on the microwave algorithms today testing various quantities of media and timing the slope for use in the firmware. Blew a fuse while testing water at 5 PM so turned it off and got ready for the opera. Libbie made soup and cheese toast for lunch then we had a lean cuisine before the performance. Left at 6:30 for the 7:30 performance. Parking was crowded because of Dora the Explorer going on at the same time. Cenerentola was delightful. The singing was amazing, the acting was quite good which we got to see up close since we were in Row C. My postcards came today in two 15 pound boxes. That's a lot of cards. Marjorie sent the Lonestar newsletter which was amazingly great.
