5 gallons of white sauce

Last winter I was asking questions about white sauce in large quantites here at Dave's Garden. Well last week I made that five gallons of white sauce in one gallon batches. One batch I put pesto in, another spinach, and the rest we left with just the parmesan and mozzarella cheeses. If I say so myself they were great. Eje or Erik, thanks a million for all your recipes and help. Fettucine alfredo for Theresa's wedding was a hit. We made the sauce the day before and reheated in crockpots the next day and it just couldn't have worked better; reheated to a wonderful creamy texture. We probably had one batch and another 1/2 batch left over. So I know Theresa will definitely use it up. So if any body wants the recipe just give a holler. I did freeze the leftover, do you think that will be ok?
