I don't think the Rugby Club are flush with cash, they seem to think Speedway is noisy though I suspect many of those who make the decisions have no idea what Speedway is (Noisy motorbikes seems to be a generalisation) and the bikers Club having their HQ on site seems to be a little bit of a contradiction, I do believe there are possibilities of staging Speedway at Portway however influential Committee members probably need to be convinced about noise issues, but with the site being next to the M42 planning may be less of an issue than at other sites, parking on site is not an issue and neither is site access, most of the other facilities are already there just needs the track, and someone to sweet talk the Rugby people that the noise is barely more than what can be heard from the motorway traffic.
Yes I remember Mike Hailwood being killed down the nearby lanes, I was a delivery driver covering that area at the time, did Mike say it was safer doing Moto GP than riding on roads (riders all go the same way).
