I've always used Overdrive and had the free ebooks, using my library, but it never dawned on me to use the audiobooks, when driving. I like that when I turn the car off (or hit stop when using at home) it automatically stops and then restarts in same place when I resume. It's like going to library day, when in school, and having the librarian read to me. haha Some of us (uhhh ME) are just slow learners.
AZK, yes, I love using it when I'm working in the yard now, also. I weeded my whole 8x8 garden, Friday, and it went by so fast. I'm not sure what my one extremely "nosey nellie" neighbor thought when I'd be smiling, commenting or snarling (depending on what section of book I was in). I love keeping her guessing anyways. Kind of my revenge for her being such a grouch. haha
