Luis Potosi for the weekend and were our only companions in the trailer park part of the hotel - which was obviously filled to capacity. Finally got to sleep around midnight. 3 May Awoke about 7:30 AM to the sound of the street noise from the main highway that passes the front of the hotel. Picked all of the animals that we had hoped to photograph and have been carrying around. Finally set out on the road to San Luis Potosi (May 70) that we had started out on yesterday. We stopped at 3 localities along the road as follows. El Venadito, San Luis Potosi. An oak forest that had apparently had the ground cover burned off and then regrown. Locality below the crest of the Sierra Sceloporus variabilis: Sam and Tim collaborated on two specimens - both Tim tagged. I got me off the rocks of the road out. 0.9 mi. E Vicente Guerrero, San Luis Potosi. An oak bounded field covered by scrubby brush & acacia. North side of road. In the Sierra. Sceloporus variabilis: Sam got me off a log along the fence and several others were seen on trees, rocks & the ground.
