text: where is a good place to hide a roll of cash in your room? where your family or a burgler wont look. get a large safe, over 1000 lb and bolt it to the floor.  it will take a lot of time and effort to get into one of them.  check into ones made to store firearms, they are the best of the safes available for home.  don't get a little one as anyone can just pick it up then crack in in the safety of there own home.  i would get one with a 4 bit key as they are really hard to pic and only some one that is vary good will be able to do it and i don't think your family or over 1% of buglers will be able to do it.  other then that, look for a wall outlet safe, not as secure but hard to notice.
