The reality is that some pros, exempt or otherwise, also bowl local leagues. Their membership dollars qualify them for association tournaments. If your association does not want them to bowl the tournament, then rewrite the eligibility requirements to exclude them from membership in the first place...
Oh, and am I the only one that finds it ironic that we are watching a thread whining about pros in association tournaments when some of the same posters have expressed a willingness for the association fees to support the PBA?
And another thought...the only person who *might* even be in a position to whine or snivel and have a possible point would be the person who finishes second and, but for the presence of an exempt member, would have been city or state champion.
