If you need anything to help I may be able to get some fox-40 whistles and possibly some brunton 9050 compasses for free. I do have a couple of extras right now and I would be willing to part with them for something as cool as this. Let me know. I may be able to find other stuff while I am looking around. I would also be willing to buy some gerber milk bags and send you the remaining amount of bags. I also have about two dozen Altoids tins I was going to list on Evilbay but I would send them to you for this project as well.
