Just don't expect those changes to all happen over night.
Everyone talks about MN Hockey like it's a single person behind the curtain making decisions over all his subjects like the wizard of OZ.
MN Hockey makes no decisions. Committees made up of members from Districts, from those District Associations, make decisions at meetings, by vote.
Think of the saying, Think Globally, act locally. It means get involved. Be active in your association get support for your opinions, take that support to your District meeting and gain support and take that District support to the State meetings. People just want change, in support of their opinion, without gaining the support of others. Certainly not majority support. How's that work? You just going to wish your change into effect?
Support for your freedom act has to happen at the Association level first. Once your Association supports your decision, because it's sensible, your Association can take it to the District where it will also gain support because it's sensible. Quit fussing and take your sensible solution with you as you actively support, and get involved with, your Association.
My initial suggestion is to allow supposed A level players from Associations that don't offer A level of play to try out for the closest neighboring Association, in the same District, that does offer A level of play. If the player makes the team you're set. If not, player returns to his Association and plays on a team in his community Association. It sounds like that is allowed in some places and not others. That should be fixed at the Association level in support of their District members that aren't strong enough to host their own A level teams.
There are many other solutions. The next best is to probably open enroll your student where you suspect they'd like to attend HS anyways. If that's your plan for HS you might as well get your player in with his future team mates on a youth team in that school area soon as opposed to later. As a mite? Squirt? Lets say first year PeeWee, or first year Bantam. If it's where your child would like to attend HS then get on with it.
It can be fun. The Mpls-Park Bantam A whooped Edina 6-0 at Regionals and went to the State Tournament. A number of the players attend school at Benilde and so play youth hockey with the St. Louis Park Youth Association where Benilde is located. Minneapolis or St. Louis Park HS probably will not beat Edina any time soon. Benilde might. The six of you should start stating your individual plan for your personal solution and we'll watch with interest. I believe there's an achievable solution for each of you.
It's the old, be part of the solution not part of the problem. As a parent, or grandparent, you should know screaming and kicking your feet isn't all that effective.
