M.F. Smith 1993 JOURNAL El Peñasco, ~5km N of Maldonado, Depto. Maldonado, Uruguay Nov. 18 and I were driven by Jito in the Nissan that belongs to the department to buy dry ice at an ice cream factory (about $30.00 US for a small piece = 30 kilos). We also filled one of the 10 liter liquid nitrogen tanks at the Casa de Inseminario, which cost about $25 US. I stayed at Enrique's house on Wednesday night since I had already checked out of the hotel in preparation for the field trip. Joe Cooke rented a car and moved his family and visiting relatives to the beach house at Alpina, leaving room for me at Enrique's house. On Thursday morning Jito picked us up at Enrique's house in the departmental vehicle. Two of the students rode along in the vehicle, and three took the bus that same morning to Maldonado. We drove to El Peñasco, the house belonging to the grandfather of Maria Luz, and dropped off our gear to make room in the vehicle. The house was enormous, with large grounds, fruit orchards, trout raising ponds, and a view of the Arroyo Maldonado. We picked up the students at the bus station in Maldonado and drove east
