I've always thought it would make good sense - financial and otherwise - for EL (and some PL) clubs to "adopt" an NL track. Obviously, King's Lynn, Newport, Sheffield/Scunthorpe & Belle Vue already have such links, but the standalone clubs could, if necessary, use the support. For instance, it wouldn't be rocket science for Wolves to use Dudley as a farm team (that that Dudley appear to need it), or Ipswich to use Mildenhall. Poole could help out Isle of Wight (they used to have a closer relationship in IOW's PL days, I'm told), and perhaps Birmingham or Coventry could back Buxton. This could be in the form of financial help, with track equipment, or giving opportunities to riders. For instance, if Buxton were to link with Coventry, the Buxton track could be used for small track practice for any new signings Coventry may make, Coventry could get first "dibs" on riders like Nick Morris & Robert Branford, Buxton would get easier access to using Coventry assets for team & individual meetings, and so on.
It's too obvious not to have been tried, but is it worth approaching the BSPA with regards to a more formal arrangement?
