What is the maximum size a tornado can be?

I live just east of El Reno (west of Yukon) and I was on the south end tip of the tornado as it passed. I was multi-cameras ready and in great position, but catching one in real life is so unpredictable due to the powerful winds and debris, visibility is near impossible. When you see it on the news, the TV stations have weather tracking teams traveling all around the outer-lying areas of the super cell - searching for the best locations to capture the tornado - and the storm chasers don't really chase the storms per se', they try to position themselves where they can get the best TV images for the news. Too far away, and buildings, trees, and traffic, interfere with getting shots of the tornado. If they get too close, they are hit with rain, hail and dangerous flying debris with no visibility and end up in a life or death situation - as what happened to Tim Samaras, his son partner Carl Young who got caught in a bad situation due to poor visability.

Point being, with storm chasers surrounding the cell from many angles, odds are someone will get great shots that you can see on TV. It creates the false illusion that tracking a tornado isn't that hard - it is very tricky and can turn bad fast.

In my predicament, I knew I was too close. I was getting pummeled by heavy rain, hail and tree limb debris, and could not actually see any tornado - and that's bad. The visibility was near zero and I was driving about 10 MPH, swerving huge tree limbs in the road and smaller branches hitting my truck. It wasn't until 2 days later I learned how close I was to the tornado and almost shat myself. So imho, I'd recommend just continue observing tornadoes on TV from the comfort of your living room in NJ. My real lesson was that it's not enough to look for tornadoes, you must watch how the super cell shifts using the radar tracker (assuming your cell phone doesn't cut out).
