Packing Lane 2--
Sell one of the pigs right away. Wait to feed the rest of the pigs until the truck has reached town and started coming back, then make sure you click on the well immediately when the truck comes back to keep them from dying. Upgrade your truck once and storage twice, then just keep collecting and selling hams. Once you get close, sell of your pigs to make the goal.

Hat Street 3--
Sell one of the cows immediately. When the truck comes back, upgrade storage and the truck and keep collecting and selling milk and bears until you get enough money that selling the cows will give you $70,000. (It helps if you buy a cat, and upgrade truck and storage fully when you get the funds) Buy an ostrich and send the plane for 5 hats and 5 cloth. Start processing feathers into dresses, selling them and buying more ostriches. Timing gets pretty close here, so you may have to try it once or twice to get it.

Hat Street 4--
Immediately buy 3 cows and a cat. Send the plane to get 12 bottles of cheese culture. Upgrade the truck twice and storage fully. Collect milks and process cheeses. Trap and sell the bears as they arrive, then sell your cheese and cows.

Hope that helps!
