I always find it interesting hearing about different parts of the country and the weather they have. Never thought of Texas as having 28 days in a month below freezing. Always thing it is warm with the once in a decade cold snap for 3 days or so and maybe a snow storm here or there. Anyway, I am one that likes the switch over as if the wife gets cold in the night... 2-20 pound tanks generally last us the spring and summer and I will take them off and put 2 full tanks on before our fall vacation. The part tanks go over to the gas grill to be used up before spring. I think I have 6 tanks in all.
