Thanks Dragon.
Stargazer, my favorite island is the Big Island. We spent a week on the Kona side in 2016 and this trip was one day at Kona and one at Hilo.
Didn't sleep well last night. Wide awake around 1am. Again at 2am and sleeping soundly when alarm went off at 3:45am. I have a class to teach next week which I'm not prepared for--yet! (I am not a teacher or an instructor but have been asked to give a class on a subject that I know well enough.)
