Yesssssssssssssssssssss and I am :) Even though it's not free... some I did on my own, my current one is half price cos I work in a college but I am going to continue even though it costs. I love to learn.. and can never get enough of learning new things :)
Indeed...there are a few earth science classes I would enjoy taking. We actually have what we call "audit" classes at our University. They are for no credit and all you have to pay for are books and lab fees.
"Go back" implies (infers?) that I was there before. No, I would not go to college if it was free. It was not cost that kept me from going in the first place, it was lack of desire for formal education.
