What other activities, hobbies, or sports do you do outside of riding?
I have to say, I have been reading everyone else's answers to this and feeling boring and lazy, but here we go!
Lots and lots and lots of books. 2-3 books a week in a good week, for work and for pleasure both. I tend toward high fantasy, science fiction, and nonfiction. I have little to no tolerance for the sort of everyday drama that usually wins literature prizes, but I do read them from time to time, usually for book club. I'm in two different book clubs.
My grandmother taught me to crochet one Christmas. I was about eight years old. I crocheted furiously for a few years, little kid stuff, and then I left off. I picked it up again when I went to college in Vermont, and it was cold all the time and trendy to do yarn work. Most everyone else knitted, but I crocheted because that was what women in my family did. I've been going since then. Usually I do blankets for friends, and lately it seems I've done nothing but baby blankets.
Another hobby from my grandmother. Any and all kinds of baked things. I go through flour in 25lb bags, minimum, and can use 10lbs of flour in one day when I really get going. I bake all the bread we eat, and it comes in handy whenever I need a gift or to provide something for work. I usually bake 3-5 different things a week, usually some kind of bread or muffin to accompany dinner.
Those are the three big ones - see how boring? We also hike, watch movies, and I research side projects. I work a LOT, so that impacts my free time. No real other sports hobbies beyond walking the dog.
