I will add my pennies
I have rattled up bucks on public land, it is not my main tool but I use it when conditions are right. Stand placement and time of year are very important factors when it comes to rattling. If either one is wrong you can rattle until your fingers bleed and it aint gonna happen. if you are in a stand that, on its own won' t produce a good buck then rattling probably won' t help.
I have also hunted for many years, and spend alot of time in the woods. I have never witnessed a buck fight. But then again I have never witnessed a buck mounting a doe - but I figure that happens once and a while
Like most everything else in a bucks life, the majority of fights probably occure at night.
I am amazed at how many bucks from from my area have busted horns, holes all over the cape from neck to shoulders and that have ripped ears.
If you don' t think they fight in your area, take a trip to the local Taxidermist and ask about the broken horns he gets - you may be surprised
