I used to read a lot, also like Taz I was an outdoorsman. Like everything else, these hobbies got pushed back so I could practice my new hobby - drinking.
When I sobered up, I got back into both hobbies in a big way. You can meet a lot of people this way as well. Gravity's idea of going to AA ca be combined with this, you'll likely find new AA friends with the same hobbies as you.
