I'll take racing any way I can get it. Circle track racing is so much more than just turning left and driving in circles, though. Have you ever been to a circle track race? I grew up in a small town, and we had a 1/8th of a mile short track there (Lonesome Pine Raceway)... you were pretty much front row, mere feet away from the cars. All the sights and sounds and smells are almost overwhelming... it's truly a great experience.
I'll never forget the first time I went to a race there. When I first heard those cars start up, my blood really started pumping, percolating even. After they made their warm-up laps and got those exhaust fumes wafting over the crowd, and finally fell into the starting formation... I thought I was ready for the start of the race. When they finally dropped the green flag, and those 12 rows of cars put their throttles to the floor in unison, I was certain I was going to fall over. It's really indescribable the feeling you get from being there and watching the race, soaking in the experience. It's hypnotizing almost.
I'll concede that NASCAR can be boring occaisionally. And, like you, I prefer road racing: F1, ALMS, FIA WRC, SCCA SPEED World Challenge; you name it, I'm there. But NASCAR is no abomination, nor is it "Fing dumb". For many reasons, the sport has acquired a reputation for being a Southern, or even ******* passtime, and I've heard those "they're just turning left" and similar comments about a thousand times each. NASCAR has ascended above and beyond the "Non-Athletic Sport Created Around ********", though... there are races all across the nation: in the South, the North, the East, and the West. It's the fastest growing sport in America (I won't even get into the "sport" debate). And if they're "just turning left", you've obviously overlooked the other 42 cars who are beating and banging on them while they're just turning left. You've also overlooked the razor fine racing lines they must maintain, the jostling for position, and the battle to balance fuel consumption, tire, motor, and break wear with speed and consistency for upwards of 600 miles. To say nothing of the physical and mental endurance involved.
I'm a fan of NASCAR and I probably always will be. I may be from the South, but I'm not a *******. Racing is just something that gets into your system, and you can't get it out even if you wanted. I could sit here and defend NASCAR all day, and people will still put out those same lame arguments you have given, and all I can do is rebut with the same lame defenses that I have given. In the end, NASCAR doesn't need a defense. It's been around for longer than I've been alive, and it's obviously here to stay and continue to grow for the foreseeable future. Instead of bashing it, try going to a race and see how you feel about it afterwards. If you still feel like it's teh suck, then fine... but don't come around here trying to convince me of it.
