Just an opinion, not telling you what to do, just explaining what I thought of when I came back.

1. Goal, for fun, for pleasure, for killing time, break hundred, break ninety, or all in to go "low as possible".
2. My equipment, will it get to the above, grips in good shape, clubs, bag, balls (Titleist?)?
3. Am I in fairly good shape, am I walking, am I riding? Do I need to lose some pounds, need strength? Will I huff and puff after 6 holes???
4. Did you golf before? No experience, some experience from the butcher at the store? Do I need lessons?
Note: Team Titleist has an instructional page with great hints, (Thanks Trilium, the last one on getting back in sync mid round will be tried next time out)
5. Whom am I playing with, myself? Buddies? What are their commitment to see you succeed.
6. Commitment, practicing once a week, playing once a week, short game, putting, all needs practice.

Golf is one of the hardest game to play, but it is the most fulfilling to me, ask anyone who had a hole in one, shot their age. met their wives/girlfriend or new friends. Its a great journey no matter where you start, just start the journey or continue the journey.

BTW, my grand uncle died on the course. He was in the upper 80s at the time. He must have had a hell of a shot. I think at the time he was enjoying himself.

So will you, Good Luck

See golf pro. Get instruction to make game more fun. They have group and individual lessons. Money well spent. If you go to range and keep doing all the wrong things you never get better. With respect. =)

Assuming you are 60+ and your son is under 45, the club loft and the shaft flex may not be ideal for you. If you are new to the game, lessons with a pro to help your swing and evaluate your clubs will be a good start. Also assuming you are price sensitive at this point that pro can also suggest various used options better designed for you. At close to $600 for a driver and $1200+ for new irons, it is a serious commitment to get fitted for new.

My worst mistake (now retired and 70+) was being self taught. A much better investment would have been starting with a local course offering group classes to start with fundamentals. Then working on a range using those basics.

Range is a good place to start! I'd suggest spending more time chipping and putting vs just pounding ball after ball. Work on keeping the ball in play. Enjoy!
