My break wasn't quite as long as yours...about 35 years...but I share your early success. I was surprised and happy how fast it all came back. More than that, I was stunned how quickly GT took me beyond where I was as a kid. That rapid progress is pretty much all due to the GT instructors and their lesson content and structure. This is one fine place!!
Have fun.
