In my personal experience, the only time I can remember hearing my heart beating in my ears was following up a wounded 9 foot plus brownie in the alders in Alaska... we eventually went back out and come in several hours later--we discovered that had we continued on our first attempt that the brownie had actually been lying in wait and had we gone about another 25 yards there would have been some serious action-- as it was, we found him dead up the trail about 100 yards further..

As to fun, bow hunting elk in the fall is pretty hard to beat..however bowhunting whitetail, antelope or muleys is a blast as well...

Being alone on the tundra hunting caribou is awesome as well..

All in all, anytime one can get out and enjoy what God has given us is a GREAT Day.
