When you go on vacation how do you keep your meter strips cool? We are going to Branson next week, and I need to be able to keep everything cool (that will be staying in the bus) while we are at Silver Dollar City. Can I put them in my ice chest if I wrap them in a cloth or something to keep them dry or can I use frio bags? I will have about 200 with me as we are going to Church camp from there for a week. I have the large frio bag and the pen frio bag for 2 pens. She is on the pump now so we wont have the pens with us. I just bought her the spibelt to wear in the theme park. All ideas and suggestions welcome.
