You'd think that a Further Education college may be a good bet, especially those running mechanical courses, also the age of those attending the college are more the age of most of the participants in Speedway, the only problem would come is if they then thought of attending Speedway there is no pricing policy to encourage them.
There's a yoof riding round my area (and probably around everybody who reads this's area), on an electric bike, more often than not only on his back wheel down the middle of the road, always wearing a balaclava... he looks like he has potential, pulls better wheelies than most Speedway riders and obviously has no fear for his own safety, just the type of person that should be steered towards a sport like Speedway and away from whatever he's currently doing with his day (and the mind boggles at that)
