Great, just had a quick look and the Hafren stages are quite interesting. Hafren 1 finished in what is now the car park....it’s quite a good downhill
Only a couple of stages to map
Someone else mapped RAC 1989! https://www.rally-maps.com/RAC-Rally-1989
Not really the most reliable source
Watch this and make up your own mind what was the likely source of the virus...
