Sorry Wayne, but I don't see any where in the 70+ posts that you have bought this to the attention of the TBA Board with nil response. Secondly I do not believe that it is the TBA Boards responsabilty to search all bowling web sites on the off chance that there is a topic they may be expected to respond too.
I do understand that it is a concern that alcohol is being served at a "Junior" event. I was at the Nationals in Hobart 1990 and we had alcohol at that presentation and as other people have said this year is no different to previous years.
So if not already, may you should WRITE to the TBA about you concerns and, if and when you do or don't get a response from the TBA then bar them for poor decision that they have made.
