Even on a hot day, the deck is still a pleasant place to sit outdoors (if one sits very quietly!). My tropical plants have been flourishing with the recent rains and humidity, but I do daily refresh of the bird bath for my feathered friends.
7/17/2019 5:00 AM 0.00 0.0 M M M When at 4 a.m., it seems that the temp never got below 77 degrees overnight, that means it’s been pretty muggy. I now hear the katydids during the night (I do keep a window cracked open regardless that I’ve got the AC on)
