Not me. Years ago a buddy camo'd his atv and lost it in heavy undergrowth. We found it. Later I managed to lose my red Honda for a short while, but red is easier to find. All my atv's have been red, since I want to find it in dim light and ride it home.
That said, I clearly remember a morning when I pushed my red Honda into some thick brush on the side of a right of way. You couldn't see it except from behind. I was hunting nearby, on the same side of the ROW, and had a big 8 point walk across the ROW between me and the atv. He didn't see me, but saw the back end of that Honda, and he knew what it was, or at least knew it didn't belong there. In a flash, he jumped across the ROW and into the brush on the other side. Then he peeked out of the brush to further examine the Honda, and I shot him.
So, red atv's are good, in that I can find them. But, deer can see them. And deer can hear them. I used to get into ladder blinds way before daylight. My lazy cousins would sleep later and then ride their atv's the 2 miles to the woods. Many times I'd be watching deer munch grass and the distant sound of atv's could be heard. The deer, from their actions, knew that danger was coming.
That's way more than I intended to share. But it may be useful to someone.
