Slow Cooker Rice Pudding

1/2 gallon skim milk
1 cup rice (long grain works best)
2/3 cup sugar 
Dash of salt 
Sprinkling of cinnamon 
Raisins if desired

Place Milk, Rice and Sugar and a pinch of salt into Crock on Hi.
 Cook for 1 and 1/2 hours. 
Stir and at this time if you like raisins add them, a couple of hands full and sprinkle in some cinnamon. 
Cook for another 1 1/2 hours keeping a check on the last hour stirring often. 
As soon as it starts to thicken turn it off if you like it real creamy,
 let cook longer if you like it thick. 

It will thicken a lot after it cools.
