I have noticed it too and my theory is this:
a) they don't usually have the distractions that city life provides for them to get into trouble with
b) They have a mom and a dad that is there for them (family ties are stronger)
c) There is usually something going on that keeps them busy besides Nintendo
The first couple of years were pricey (camo, clothing, etc). I probably have spent close to $1000 over the last three years but after that just maintaining what gets used up (scents etc)
I'm happy to report that I got my first buck of the season this morning! It is a young 2x2 that will look wonderful next to the potatoes and gravy. We were right in the middle of a nasty storm that blew all night and the rain and wind were still howling this morning. Didn't think I would even see a deer let alone shoot one. By the way, I like backstrap fever the best so far.
I would choose the fleece, especially where I hunt. While the weather here doesn't get that cold, it does get damp. Goes right through me sometimes making for an uncomfortable hunt
