Walking or sitting for deer?

[Joe Btfsplk]

I only have two years experience hunting whitetail, and would really like to harvest a mulie if the draw works in my favour one of these years. Last year, I tried walking the area, and scared up a moose cow with two calves, who knew I was there. She was booking it in the opposite direction. I saw no whitetail at all. Getting tired later in the day, I sat in my favourite little wooded area looking down on a slough, and out walked a beautiful mulie doe about two hundred yards away. Of course, I don’t have a tag, so all I can do is look. She rubbed salt in the wound by coming towards me until about 25 yards away when she sighted me and pronked off. I did not see a whitetail at all.
Question; is the option of walking better in general, or is sitting better? Does it depend on terrain or my physical condition? I hunt where there is vehicle access to most areas, so I will not have to pack out an animal. Keep in mind my level of experience and the fact that I am 68 years old.

By the way, was it just a bad year for me or are whitetail numbers down in some areas? I did eventually get a small doe, but there was not much meat in the freezer this season…
