Amateur Radio. Check out Parks on the Air and Summits on the Air. Essentially you take your radio to a park or mountain summit. Setup your gear and try to make radio contacts with others. Good communities behind both and likely some people in your area doing it.

- It is relaxing and something outside to do. - You can meet others locally who are into it as well and also meet people as you make radio contacts. - You'll need an amateur radio licence which can be a new skill to challenge you.
