Try different items than water. I usually have Propel in my car, it freezes, but not completely all the time. Just a thought. Gatorade is about the same. So there are probably some others I haven't tried that won't freeze completely. Items with some sugar or sucrolose (sp). Tried just wrapping it up in several layers of blanket? I'll have to do some experimenting.
Really dont want my 1 year old drinking gatorade or that type of drink. I am going to try wrapping them in the extra wool blankets we keep in the cars and see if that works.
The enemy of my enemy...... Is just one more set of targets to engage
