I am not sure that you can call volunteering a hobby; but it can be very fulfilling, if you enjoy doing that. When I was in Idaho, I volunteered at the local Sheriff Department. Mostly, I worked in the dispatch area, and I would help with the filing and things that needed done that dispatchers didn't always have time to get taken care of, especially when they had a busy night. Sometimes, I got to help with the actual dispatch, and I really enjoyed that part. When we had a local event, like the county fair, then the reserves were sent out as part of the security detail for the fair. I didn't wear a weapon; but I had my badge, uniform, and 2-way radio, and I could help people who needed information, or had lost a child or other family member. This was a great plan, because we could have more of a security patrol at the fair, and the regular deputies could still do their job of patroling on the road as well. Sometimes, we would ride along with the road deputy. I would go along when they were transporting a prisoner somewhere out of town (to another jail or a prison somewhere), and that helped the deputy out, and still only used up one of the regular deputies to do it. I think that there are all kinds of places that need volunteers, if a person is interested in doing that kind of thing. Churches and rescue missions who feed the homeless always are glad to have help with food preparation as well.
