I'll state the obvious ... once the bucket has been "used", the suggestion is to refrain from storing the supply of toilet paper in the bucket - at least the clean stuff. <img src="/images/graemlins/grin.gif" alt="" />

Also, don't forget to pack a full box of 13 gallon kitchen garbage bags - the white ones. You can line the bucket with those, then, once "filled", you can twirl & tie the bags and then store them in a double-bag to try to keep the odors down.

People who travel to remote areas with no toilet facilities and an inability to dig latrines (such as mountains or other areas where digging is impossible or hazardous to self or nature) use "poop tubes". These are large plastic PVC pipe which has an endcap glued onto one end and a screw-access cap glued onto the other end. Users do their business in a plastic bag, seal the bag, and then stuff the bag into the "poop tube" for storage until the contents can be properly disposed of.
