I think I like Quasar so far (hey, that rhymed!)
Interesting that someone mentioned Quebec since I work there I live in Ontario and work on the Quebec side....so definitely my co-workers would LOVE it if I picked that name!
Quebec was my suggestion as I live here in Quebec Maybe we'll meet someday. And yes I can assure you that your co-workers will LOVE you if you name your filly Quebec and so do I !!!
