Gonna need those oxen to haul the wagon out West! I think I saw 'em hangin' around the neighbors' cows and oxen. You'll also need some sawhorses to support the yoke when you round 'em up.
In-Game Hint
Sawhorses can be crafted inside the Barn. The Barn can be purchased in the Market. Don't forget to leave you neighbors some tools once you visit... they may return the favor.
