What is Buck fever?
If it is acting like the guys on TV then stop watching TV.

There has only been once in my 42 yrs of bow hunting that I actually had the shakes.
That was when I had a water Buffalo at 10 yrds with nothing between him and me except a Gum tree and a briar bush and I knew if he busted me it was over for good.

Back in Australia we did not have these hunting shows or videos telling us how to act when an animal came in.

IMO there was no such thing as Buck Fever until hunting shows and videos started trying to get more excitement into their hunts and now that every one watches them they have planted that little seed in your head as how you MUST act when a buck comes in.
