Journal Hofner, M.S. 1977 10 km S, 2 km W Sombrerete, 2130 m. Zacatecas, México. 22 July (cont) daylight hours. Perhaps an early afternoon rain explained our success yesterday afternoon. By 1400 we had a mere 16 gophers, none alive. I finally brought in a live male, so we injected him and later karyotyped. Total Catch: 17 Thomomys umbrinus 1700 we broke camp and drove to Sombrerete. JCH attempted to call home (Jimmy's birthday) from a "Farmacia" but the place was so busy and the people so rude (not purposely, we think), that we finally left and headed for Fresnillo. We gassed-up in Fresnillo (the main highway bypasses the town). 1900 arrived in Zacatecas, an old Colonial city. (dirty and dusty). A huge, ornate Cathedral sits in the center of the city. We called our wives from the large hotel to the north of Zacatecas. Every- thing is fine with Davey, Emily and Julia! We then ate at a rather expensive place (with rather poor food) and drove about 10 mi. 5 of town to camp along the highway. Cool, clear evening. We were very tired and looked forward to a restful night.
