I will be missing opening, because my niece is having a birthday. My brother died a few years back and I kinda fill in for him on such occasions. Normally, I would feel bad about missing opening but with this heat, heck I would rather go to the party anyway. Might go Sunday afternoon....but may not. No rush this year. It is just too darn hot.
As for acorns, there are tons on the trees here in Southern/Middle Tn but have yet to see any dropping.
