I drove up Pikes Peak in 1977 when it was all still gravel. I was having fun kicking the tail out on my 73 Challenger, until I got pulled over by a Park Ranger in an unmarked 4wd Suburban. He gave me a stern talking-to but let me go with a verbal warning. On the way down I kicked the tail out a little but it scared the daylights out of me and I quit doing it. That's when I realized that gravity was my friend on the way up, and my enemy on the way down...
