Like everyone else her, I was actually decent in my early 30s. Got down to a 7-8 handicap. But then my kids arrived, and I played only sparsely for 20 years....you know, soccer tournaments and all.
Even though I am still working, I have picked up the game again here in Florida.
But, as was said, it takes a while and a lot of work to get it back. I might be a 11-12 now, but it is getting better.
The cool part is, the equipment has improved dramatically and I can now hit the ball farther than in my 30s. If I could just control the damn direction......
