In the event guide, it states in 2.c. “In addition to a binder and field guide,” but no where in the event parameters does it state which type of field guide is allowed or if one is actually allowed. So, is a field guide (Audubon, Simon and Schusters, etc) allowed?

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