I have been hunting this scrape off & on for 4 days ..,this evening I went by and checked the?

During rut bucks will rub their tarsal glands together many times til they bleed, this is probably what you saw. I've also seen a buck that had been wounded by another deer battling over a doe go right back to checking his scrapes.

Sometimes Does pee in the scrapes as well, especially when she's ready to be bred but no buck is around. Could have been blood from a "ready" doe.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
