Not sure it is a hobby anymore- more like a 2nd full time job, but Jim and I run a small non-profit Italian Greyhound rescue in Tulsa, which means there are always between 9 and 12 (average) dogs in the house, in various states of socialization.
I am also a voracious reader, and love to cook and bake. I knit when I just want to do something comforting, without having to think about it.
