You are allowed a 3ring binder and a field guide but does the guide have to be in the 3 ring binder and does it have to be in rings, can it be removed from binder, if not can it have a chain to connect the binder and guide permanently?

Field guides are an optional resource that teams may bring to the event if they choose to. The field guide is not required to be contained in the binder. It must be clearly marked as a field guide and not just a book on rocks and minerals.
