I have used new one and five gallon paint cans for caches. Be sure and carry the proper tool to open it. <img src="/forums/images/graemlins/blush.gif" alt="" /> They seal very well.

I would skip the moth balls.

I have used engineering tape to mark an "attack point" that starts a compass bearing to the cache.

I would not want to carry a 5 very far.

I have hidden the cache within 50' of roads, but in dense thickets and had no problem.
