first thing's first.... you don't have to be able to drag a knee on the street to do a track day. It's not a prerequisite. In fact, I've been doing track days and racing for a few years as well as instructing at the track now and I've NEVER put my knee down on a public road. The only place my knees have touched is the race track. If you're dragging them on the street you need to back off because you're riding WELL beyond reasonable limits for the street. There are WAY too many variables for ANYONE, but especially someone who doesn't have any significant training to be riding like that on public roads.
The best tip i can give you on how to drag a knee is do it at the track. Do it at the track and DON'T make dragging a knee one of your goals. If you go out on the track and your primary goal is to scuff your pucks, guess what... it's probably not gonna happen... or if it does, it probably won't happen the way you want (ie, you'll scuff your knee... followed by your elbow, hip, shoulder, "O Ring", hands, thighs etc etc etc.)
Instead of being concerned with planting a puck you need to concentrate on the basics... being smooth, being loose, being consistent and using proper technique. THAT will lead you to scuff marks on the pucks.
The reason for that is because you only have so much brain power... if you go into a corner thinking "DRAG A KNEE, DRAG A KNEE, DRAG A KNEE!" cuz guess what, it probably WON'T happen because your brain can't think about the things you SHOULD be thinking about.. like "be smooth, be loose, get into the proper body position, break here, turn in here, carry good cornerspeed" etc. If you do all that, then it'll put you where you need to be to get the pucks down.
