I emailed Hawkline to ask if "Farm Force" was theirs and got this response:
"Thank you for your inquiry. The Farm Force by Hawkline at TSC is our product. In Minnesota this would be your best source to purchase Hawkline products.
Best regards,
Bob Lotzer
Sales Manager
Hawkline Nevada, LLC"
I've sent an email to Tarter Gate with the same question. I am thinking that Farm Force is a TSC marketing brand and that it is sourced from either Hawkline or Tarter Gate (or maybe even other makers). I have no idea why the Hawkline flavor would be offered in Ohio and Minnesota while the Tarter Gate flavor would be offered in Michigan.
