Earlier in the day I saw 30-50 nectaring on the alfalfa and asters. I knew there was a cold front coming through with rain in the morning, I went out around 7:30pm to find the roosts. Everyone was clustering very loosely and spread out on the north side of the chinese elm trees. Temp at 7:30pm was 81', SSE wind 8mph, dew point 69'F, barometric pressure 29.62"
