Im not totally familiar with the orange requirements on blinds in IN but it might be required on public land and not private land. I do believe in IN during gun seasons hunters are required to wear orange upper, outer garment and hat. But after the fact the CPO can't really do anything as the hunt is over. I do not know IN law as to distance from dwellings but in IL it is 300 yards from inhabited dwelling unless you have inhabitants permission.
Personally I would have done the "feeling out" before I called the CPO and voiced concern about no orange on his body for obvious safety reasons. Not that you would be shooting on his land but the safety commandment of knowing what is beyond your target.
