Old?
At our field there is no age issue. I'm 46. Started last year. I too wish I had started earlier. I've made some great friends. I really look forward to the weekend morning breakfast at the diner.

Expense?
Sure, I've spent a few bucks. But I can remember spending just as much for a day of fishing.
It can be expensive if you let it. Get a veteran to help you. I haven't found anyone who can fly, who doesn't drop what he's doing to help another flier, or potential flier. Once you're into it, you'll probably find a few next plane bargains in your own club membership. I've seen several of the veterans offer bargains to a local member who will enjoy the plane. But they won't offer it to the guy who buys a plane a week because he can afford it. If someone wants to play, a plane will show up. It might need a little TLC, but the guys will also help you get it back in the air.

Get involved in the club.
There's always someting that you can help with. It's great to share with your kids. My boys have no interest in flying, but the enjoy going to the meetings and hearing the stories.

I go on and on, but damn, this is fun.
