I ALWAYS carry a cooler full of water bottles in my car. I have to due to the heat down here.
Oh glory I know what you mean. I'm down here, too. I cannot go anywhere without practically an ice water IV drip. I just get a kick out of people at work who carry their water bottle around from air conditioned room to room. I guess with our unhealthy habits being taken away something has to replace it! LOL! I mean go for it, water is a good thing.
