RE: 3D....How do you find out if you like it or not?
It sounds like alot of us are competitive be it Golf, Archery, or whatever your hobby is.
I also think I could compete with many in a few different sports if I had the time to put in the needed practice.
The trick amongst us family guys is to be good... maybe pretty darn good, but not sacrifice the family life. Maybe the guys who are "that good" top notch (let's use 3D) got that way when single and time allowed them to be that good. It was thier life. Now as they age they can stay at or very near that toplevel with merely "maintenance" practice.
I love to win as much or more than the next guy. I could shoot with very good guys and not emabarrass myself, I could golf with top guys and not embarrass myself, would I win? Not likely, I'd have to be hitting on all cylinders to give them a run. But at the end of the day they'd shake my hand and say "well-played". They'd go back to thier range (Golf or Archery) and I'd walk in my Home smiling ear to ear and tell the days tales, to my family!
