dont think anyone actually goes mate,far as i am aware they dont have compressed air?
give them a call see what numbers they get down there
personally id go to campaign in cobham or SPC dorking
Campaign is the place I usually go to but sadly I will be on holiday for the August walk on so I was seeing if there was an alternative (I did also go to Holmbush a few times but that is now a pain to get to after I moved house).
