My sister-in-law turned me on to a blog that I think is just terrific: Margaret and Helen. The name is a bit of misnomer; Helen seems to do most of the posting, but her grandson encouraged her to start the blog so that she could keep up with her friend Margaret.
Anyway, Helen is 82 years old and says — er, writes — exactly what she thinks. Good for her, whether or not you agree with her politics (or her, um, salty language).
