I had my first beer while operating a tractor about a week ago. My new tractor has a built-in cup-holder, and I had a powerfull thirst, so I thought I would give it a try. Before I even made it to the end of the lane, the beer popped up out of the cupholder and landed on the operator platform. I grabbed for it, putting myself and the machine at some risk. In this case, it would not have mattered if that can had soda or Coors light in it for I had only taken the first sip. I dont think cupholders on tractors are such a good idea. As far as beer and chainsaws go, I dont normally mix the two, but when I have on occasion, it has definitely improved my accuracy. After 3-4 beers, I can litterally lay a tree down on a dime, every time, and never come close to getting a bar stuck or anything else like that that slows the process down. I am the same way shooting pool. If the liquor level is perfect, I am nearly unbeatable in 8-ball. Take it too far however, and my 5-year old kid can beat me. I dont want to find out what happens with a chainsaw when taken too far, which is why I dont do it anymore, even with my past sucesses. Having kids will force most folks to reduce risks, as there are others depending on you. One other place beer will hurt you is bass fishing. I have never ran into anyone who could consistantly out fish me, and I can almost feel a fish breath on my lure most of the time. I loose that ability after less than one beer, which is why you will never find any on my boat. If law-enforcement could harness this concept "ability to detect a fish's strike" it would be far more accurate than a breathalizer.
