Welcome them with open arms and an open mind. I think theyd really like the grouse and elk steak on rice. These are two very delicious meals. Heck have them help you prepare the dinner as well. This will open their minds as well. I wouldnt go into too much detail of the hunting aspect but just kind gently bring it into subject slowly. Dont go into the "I blew its friggin head off" story. This should be an enjoyable time for all of you.
