Relatively speaking

I had forgotten to post about this, but I was told by my favorite aunt and uncle at my sister’s 40th birthday party a couple of months ago that one of my cousins, David Randall, bowls in a league at Westgate Lanes with his wife, Debbie. I finally contacted the wife today and found out that they bowl in the Friday night league. She had forgotten the name of the league, but I was able to deduce from the league schedule as posted on the lanes’ web site that it was the TNBA mixed league. I am now leaning toward joining that league after the holidays (provided I can replace a dummy on one of the teams), as I’m used to the format (4-person teams…the league I spent the most time in, the Tuesday night His & Hers mixed league, is now a doubles league) and I’d be sure of getting a ride home from my cousins. My only question is if the TNBA league is also sanctioned by the USBC, as I’d like my average in the league to count as an entry average for tournaments down the road.
