Good stuff. Thanks!
You may want to chat with your local Farm Bureau. They advocate for farm families at the local, state and national level. Trust me, congressmen know who they are and who they represent. The mere mention of a large organization quickly gets the attention of congressional staff. :)
Another potential avenue to try is contacting one of your senators. Depending on what committees your senators and/or congressmen are on can greatly influence their ability to help you.
