Got back into fly fishing. I started when I was in college but kind of just ran out of time to practice and never really had many friends who did outdoorsy things.
My new job has me on-call a few months out of the year and it allows me to sneak away and get outside at a local park while being able to easily make it back home if needed (something that I can't easily do on long bike rides).
I also recently started tying my own flies which is something I found enjoyable. Its nice to create things outside of a computer screen occasionally and I have something concrete in my hand within an hour.
