Cool Clare ! Isn't it GREAT :-). I saw it about 3 yrs ago in FL. Got up at 4 am and laid out in the yard and counted about 150 streaks and then got tired of countin, lol. Was up late last nite hopin to see something but nothing yet.
Burst your bud of calm and bloom into hysteria :-).
I'm going to look for them at home and on vacation - but we're forecast to get rain!!! The weather from Florida may head inland, hope all you Floridians are OK.
