Good question! I took hunters safety back in the mid 70's and lost it probably 10 years later. Every state I have hunted in I have grandfather claused in and not been required to have the card. However I am thinking of hunting Elk in Colorado this fall and I need to have one regardless of age. I took Hunters Ed when I was living in Michigan. My question is would they have it on record and who would I call in Michigan to find out what to do. Sorry to but in on your post but it just reminded me that I need to get my hunters Ed card before I go.
