Yesterday I belly crawled to with 75 yards of a bedded elk herd. Grey wool britches, orange vest, and a blue flannel shirt underneath. Had a winchester 30/30 lever action open sight. No stupid scents, no bait, no trail cams or fancy hunting gear. It took me 4 hours from when i first saw them to get into a shooting position. Unfortunately, there wasn't a shooter bull in the bunch, and i snuck out undetected. Just because you use all these idiot scents and what not, don't assume others do. Hunters sold their souls years ago to the almightly dollar, I find it refreshing that some are starting to backlash.
It would be a very safe bet that you, and every one else here, have used in the past or will use in the future some form of bait. For Gods sake, native Americans have used different forms of bait so don't act so holier than thou about "bait".
