Turning from the A5 at Capel Curig towards Llanberris and Snowdon the road becomes a coiling snake of motorcyclists. ( By 1965, the Dragon needed a bigger venue, and so it moved back to the Llanberis valley, to a site now known as the Glyn Rhonwy business park, but then more commonly known as Glyn Padarn.Sited between the mountains and Padarn lake, Glyn Padarn had started life as a series of slate quarries, following the exposure of the slate seam up the hillside.Recent years have seen the Dragon move around again - Beddgelert, then Llandwrog Airfield (famous as the birthplace of the RAF Mountain Rescue Service in the 1940s, and less famous for storing the entire stockpile of German "Tabun" nerve-gas bombs after the war...) and back to Capel.
There was even a huge underground factory, which partially collapsed during the war years, burying quite a tonnage of explosives.
I'm writing this the week before the rally, in February 2003, and will be at Glyn Padarn (or Glyn Rhonwy as it's now called) for a few minutes of sentimental heartache, sometime over the weekend.
Maybe I'll see you, or the ghost of your memory fleeting between the trees.
And anyone at these early Dragons will also surely remember the "Dragon Parade", on Saturday night, when the headlamps of hundreds of bikes wove a magic ribbon for miles over the old mountain trails.
The old roadways are still there, overgrown and largely impassable now, but despite some new industrial developments many of the trees at the heart of the site still remain.
