Re: APOD assessment poll #8
I found APOD in March 1999 through a friend who sent me a link to a picture that fascinated & awed me. Since then APOD has been my home page. I never start a workday day without taking a look at that morning's picture. Thanks for all the years of wonderful images and a great start to my days.
