  • Clark cited University of Vermont research showing New England red oaks moving a tenth to three-tenths of a mile per year while climate moves four to six miles per year.

Winton Motor Carriage Company

    “the two-cylinder chain drive engine had 20 horsepower. And my friend, a John Deere X300 series riding mower has 22 horsepower”

  • Clark suggested Crocker recommended a Winton because Winton had already shown confidence in its cars by attempting a cross-country drive in one.
