Well I work from home, so I'm not exactly watching them full time. But I do have hobbies, and as my children get older I hope to share more hobbies with them. Most of my hobbies are outdoors related. Hiking, camping, fishing, gardening, etc...
I like camping as well. My children are big enough to take them camping but not that big to go serious hiking. As well as you, I'm looking forward to that.
I love to do wood crafts. Not anything elaborate but I've made a few shelves and things like that. I would really like to get into it hard core but I don't have all of the fancy machines to use. I've slowly been adding to my power tools but it's going to take some time.
