I figure I'm a pretty stinky SOB and use my thermacell religously during the early season, because I figure if I'm not smart and play the wind they are gonna smell me with or without it. So the options are do not use and get eaten up and find yourself figiting and twitching, use an unscented bug spray (which we all know are as unscented as my socks), or use the thermacell and stay motionless and play the wind like you should be in the first place.
