To earn money really fast when winter comes every day take your basket and bring it to the mine cave that only opens in the winter and dig for minerals and when ever you get one put it in your basket (do not pick up the junk minerals and put them in the basket because you will not get any money from it) keep doing it until your basket is full. Take the basket and leave the cave and bring it back to your farm and put all your minerals in the shipping bin this will give you over 2,000 dollars a day for the winter!
