I was thinking about packing in the dry ice at home,that way I can take my time and try to make it last as long as possible.If I do purchase it on the way up should I package it any certain way?

Dry Ice changes directly from a solid to a gas — sublimation — in normal atmospheric conditions without going through a wet liquid stage. Therefore it gets the name "dry ice."

As a general rule, dry ice will sublimate at a rate of five to ten pounds every 24 hours in a typical ice chest. This sublimation continues from the time of purchase, therefore, pick up dry ice as close to the time needed as possible. Bring an ice chest or some other insulated container to hold the dry ice and slow the sublimation rate. Dry Ice sublimates faster than regular ice melts but will extend the life of regular ice.

Its nearly impossible to make dry ice last. It doesn't work like that. If you take it out of its frozen state at something like -40*F then it will begin its slow decline. Its something like 1-lb of dry ice lasts one hour.

HAving a quality cooler is more important that having dry ice. You can pick it up in several places along the border. Border Bob's in Int. Falls is where we get ours. The ads they hand out on the street usually have a coupon.
