From the Hammonds website: "In order to encourage local harvesters to pick them up, the starting price has been set at an all-time high level -- $13.00 per hundred pounds (after hulling) across the entire buying region."
Hmmmmm..... I have a bunch of walnut trees. Conservative estimate time: If I can pick up 15 per minute, that's 900 per hour. If it takes 2000 walnuts to get 100 lbs hulled, then in one hour that 900 count is ~45 pounds. If they pay $13 for 100 lbs, you'd only be making $6/hr, without any overhead or transportation costs. dangit.... nevermind.
Depends what % of the walnut weight is in the husk, I guess. If it's half (the assumption I used) then that's no good. If it's only 20%, things look a lot better.
