Meanwhile, place bacon in a large, deep skillet.
Cook over medium high heat until evenly brown. Drain, crumble and set aside.
When potatoes are done allow them to cool for 10
minutes. Slice potatoes in half lengthwise and scoop the flesh into a large
bowl; save skins. To the potato flesh add sour cream, milk, butter, salt, pepper,
1/2 cup cheese and 1/2 the green onions. Mix with a hand mixer until well
blended and creamy. Spoon the mixture into the potato skins. Top each with
remaining cheese, green onions and bacon.
