I didn't know about the bullet holes Frelon! I mostly walk along the western side of the airfield between Waterhouse Lane and Hillcrest Road but in the last couple of weeks have used several other entrances to the site and discovered the rifle range wall in the trees on the southern edge. Sadly graffitied...
I had to laugh at a comment on one of the Kenley sites that cyclists are doing 30-40mph around the peri-track - I seriously doubt it!
