That is awesome. 147 sounds about like what my average would be. That was when I was bowling regularly. Now it is probably even less I would guess. I feel like I have had those games as well where everything was just going right. I was still never able to break 200 though.
I am glad that have been able to find even more joy again from this. I know you enjoyed it before, but having that weight off your shoulders has to be awesome.
