Since you got into golf, have you thought about softball? You can play 2 weekdays in the rec league and on Saturday in the neighborhood league, or all three days. We have the largest softball league in the USA, nine diamonds and 2500 players.
If you want something a little more demanding, how about a pilots license. It's only about 30 minute ride over to Leesburg Airport and once you're licensed, they have fly-ins to other airports all over the state for breakfast and lunch.
If you want to keep your feet on the ground. They're bike groups that have rides to various locales. If you have a problem with balance, there is the Harley and Honda trikes or a Can-Am Spyder.
Myself, I use to fly but it was too expensive to stay with it. Now, I play golf, softball and go to MVP Athletic Club at Brownwood 4 or 5 days a week. I didn't even mention all the things you can do on the water or the beach.
