good luck finding the tune – brings back memories seeing that location (and I see xray alpha 97 was about as usual…)
when I posted ages ago about cycling to Cholsey it was reported by a top criminologist from University of East Anglia as “the extent that folk will go to to attend illegal raves”. FFS I lived in Caversham at the time, its only down the road!
BTW if you ride a bike with 700c x 25 wheels and not a MTB don’t try the ridgeway, you only end up going over in the mud due to the ruts, use the B road instead….
