First time bowling post-op

I just had my first night bowling since my surgery June 3, 05 (3 1/2 months out). To confuse things a little more the alleys were changed over the summer from natural wood to an artificial surface. My super hook was more of a straight ball and it took two games to figure it out. my third game was a 213 but I only had a 470 series. My abdominal muscles were a little sore last night but feel fine now. best wishes, Rich
