Joe Niekro's website looks impressive...I do not have time to read/study it now...re: the dates...
Thank you for giving his name out... somehow I think someone else offered this info a few months back because it triggers a mini-memory...but the name Joe Namath came up in memory...
Then there is this BAF and the TAAF in CA...and, perhaps there are more organizations/associations... ?
I remember that in May, the BAF sponsors their Walk-a-thon in Boston ...somehow think the September timeframe is also their planning...
