I too feel that tracks are a little too dangerous, yet boring.
This story relates to a modern track, not a vintage track, but it highlights what can and does happen at some tracks.
The track in question was originally laid out in consultation with a retired Pre rider, and made great use of the natural terrain available to it. It had some whoops, and it had some man made jumps and table-tops, but all done in a way that even an old Enduro rider like me could take his KTM250EXC out to play and still enjoy the day immensly.
Then the track prep got taken over by B grader (who wanted to get into A grade) and first more jumps were added.. "Not enough jumps on this bloody track!" The B grader enjoyed his jumps.
Then all the up and down ramps were drastically steepened, and the lips sharpened to a knifes edge (including a couple that were immediately on the exit of corners so there was no run up).. "How's anyone suposed to learn proper jumping techniques if there's no insentiive to time the table top properly!"
Then all the single jumps around the track were enlarged, and secondary jumps added in the landing zones (so that if you didn't make it, you endo'd). "Just jump further and you'll have no problem!"
And eventually the enjoyable, mostly natural terrain track became a stop-start, point and shoot jump fest that lost about 65% of its weekend patronage, but the track prep guy and his Supercross wannabe mates enjoyed..
