I'm feeling warm in my un-airconditioned office, the brain is boiling, so I am sorry, here comes a 'hare brained' idea.
Perhaps a way for young (i assume he is young) Snyper and his mates (assuming he has mates) to get some valuable speedway practice in, up in Scotland and perhaps the same for the rest of the UK, is for one or all of the speedway frame manufacturers to develop a sprung back end, yes a bit like Grasstrack, but to keep the bike more like and to keep the feel of a speedway bike and then for the youngsters to approach a friendly farmer who will let them use his land from time to time.
The lads (and lassies) could mark out their own track, cut the grass off, if possible, roll the track, after a while the track will be something like a speedway track (a slick speedway track), but it will give the youngsters a chance to practice and more near to where they live. The cost would be far cheaper than the travelling expense and the cost of entry with the more organised tracks. The farmer, I don't think, would need planning permission, but obviously you would want a field which is unlikely to offend anyone nearby.
