Just be careful with how you store the creatine. Used to take some with me in a bag, whenever i went on trips.
A small plastic bag full of fine white powder does not look like creatine, and most people don't even know what creatine is. Once was stupid enough to take a bag with me crossing the border. Thank odin they didn't pull us over for a search!
Creatine costs like nothing. I would just get another pack/box/bag/bucket and keep one at each place.
