Hooty, find a log, roll it over dig under, roll back over, gps it. If you leave it out BB will get it; if you don't dig it down the bears or raccoons will find it.

No flagin tape just compass or gps IME

double zipbag is enough, use a regular grocery sack on the exterior to keep out the wet. Find a nylon bag that a gallon can fits in as once you bury them they get rust on them and that stains your gear IME.

Find a special looking bush or small tree shape and dig near it, makes em easier to find without a neon arrow pointing down to the hole <img src="/forums/images/graemlins/grin.gif" alt="" />
