RE: How important is sent, really...?
I'm big on scent control during hunting season, I even go a little overboard, but to each his own.
As for seeing deer, I see them ALL the time. During spring and summer, the wife, kids and I will sit together in a blind or in our two man stands and watch them feed, etc. in our food plots. No scent control.
BUT, during bow season, to ensure a close sighting and opportunity to harvest one, I take extreme measures in the scent control department.
During rifle, I still do, but admit at times I may not go to such lenghts to cover my scent, I just play the wind more.
Bottom line, if your seeing deer or scenting up to your hunting area, thats great. Hope everyone has a great hunting season, Good Luck to all!!
