Rather than just venting on this message board, parents who think age verification is an important issue should contact the following:

US Lacrosse - http://www.uslacrosse.org/about-us-lacrosse/contact-us.aspx

They have a greater impact on town teams but US Lacrosse & their state chapters can put some pressure on tournament directors (esp. if tournaments & teams rely on US Lacrosse insurance). Kids injured by older kids will result in lawsuits and this will impact US Lacrosse insurance.

Tournaments - https://www.google.com/#q=lacrosse+tournaments+summer

While some tournaments are starting to address the age issue, most are only focused on grade-levels (because this is what college coaches are focused on). Nevertheless, pressure by parents & teams can force tournaments to relook at this issue. If you have played the Edge team in a tournament, contact the directors of those tournament and discuss why this type of club behavior can result in injured kids. Moreover, you should also contact local tournaments because local parents & local teams will have a greater impact.

College organizations such as NCAA - http://www.ncaa.org/about/who-we-are/contact-us

Until college coaches stop recruiting 9th graders, some parents and clubs will have an incentive to game the system. College organizations need to be prodded by parents & teams and encouraged to revise their recruiting procedures.
