While the odors are reduced by bags the smell is still there - point in case commercial freeze dried meals in sealed packages will attract squirrels! The smell is transfered when you handle food.

An Ursack is a good lightweight choice - but be sure to learn how to use it right, before you take it out. The knot is important. I have had many mornings finding my Ursack covered in little poopies. The mice/squirrels/etc will spend all night trying to get in and poop while doing it. <img src="/forums/images/graemlins/smirk.gif" alt="" /> I have 2 Ursacks..going on 7 years now with my oldest one. And as a benefit you don't hang an Ursack, so no skill needed.
