not a bad guess considering it 3% now, and 15% last year. China has the worlds ree nuts in a vice grip. 10% easy, and potentially much higher in coming years.
A couple of years ago I was hunting grouse with a buddy. We parked his pickup at the base of a branch road off of a dead-end logging road. When we came back, the battery had been yanked from his truck - but we could see from the tracks that his vehicle had continued UP the road. So we pulled a chainsaw out of the lockbox in the back of his truck, and I dropped a tree across the road. The we waited with .22s and kindly asked for our battery back - then left him trapped behind the log.
