Tips For First Time At The Track??

Check out the riding techniques forum here on DRN.
You've asked a VERY loaded question that would take a long time to answer :)
Everything you could posibly want to know about riding is in that forum.

Bottom line?

Take it easy
Hold your line when faster riders come around.
Pull off at designated places.
Don't cut the track to play on one jump (assuming there are others are on the track).
Don't crash.

Another way to explain holding a line: just don't attempt to change your position on the track to "move out of someone's way". Let them decide how to get around you, and don't "change lanes" on them once they come up behind you :)

Jay, where I was going with that was; as long as there arent a ton of people there spining laps, you have experience on tracks, where and when it's safe, etc. My comment was directed more at the kids that find the biggest jump on the track and do it over and over, all day. Eventually, they are going to cut someone off. They aren't there working on sections, just that one jump.

Best example of that was at Buffalo Rock in Illinois (Wardy actually built that track); large jump, kids just lining up, vitually on the track... one takes off, decides to roll it, rider out there doing laps lands on him. It was freakin ugly. Sure that could have happened either way, but the kids got so caught-up in doing that one jump that they got really sloppy about watching for other riders. Had the kid not just pulled on the track, the rider would have known he was there.
