I think the sport is dying out, a real real shame... I remember when it used to be the Lombard RAC going up to the night stages with my Dad when I was a little lad, freezing my ass off, but then hearing the warning whistle for the first time and seeing a Sierra cossie at full chat thundering towards you at ridiculous speeds, huge bangs of unburnt fuel as it slowed down for a hairpin to then slide and dissapear off into the night. There in that muddy freezing forest, a petrol head was born!
Such a shame if other little lads / lasses don't get to experience that early rallying memory :(
