On Sept. 5th a bit after 8 PM, my sister-in Law, Niece, her fiance and I were out on patio when we started seeing them, suddenly there were at least 20 all glowing in different shades of colors. We watched for a good 20 minutes just enjoying the show as they were like dancing glowing all at once. Truly amazing to witness. So much so thoughts of getting pictures never entered our minds.
