Sorry for the delay, I was in Ottawa looking for a place to live. Moving day is 25 Aug so far.
I don't think they were ranked in any particular order; I think they just asked a bunch of outdoor writers/guides to submit 5-10 ideas. For what it's worth the top 10 were:
1: Catch the brookie of your wildest dreams;
2: Know how to land a float plane
3: Learn how to use GPS
4: Remember how to use a compass
5: Master the diaphragm turkey call
6: Take up bowhunting
7: Make a fire the old-fashioned way
8: Learn how to fly-fish
9: Figure out all those damn knots
10: Go fishing with Bob Izumi (or whoever your angling idol may be)
I thought the last 2 were pretty interesting:
100: Snorkel alone with sharks on the Great Barrier Reef;
101: Be ready to die a good death (see above).
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
