OK some will be happy to know I replaced the faulty temp/hum sensor. I have my old high response Sensirion SHT-75 in there until a new Davis one arrives. This has a lot less thermal mass than the Davis so it responds quickly to temperature changes...probably similar to ASOS except ASOS averages its official readings over a 5 minute period to smooth the data out.
Rattlesnake Island on Winni has a ton of those types of nuts/hulls. I haven’t been up there since the late 90s so I don’t know the species, but they were hickory. My friend called them pignuts, but they may have been shagbark or shellbark too.
