Hi all both tracks are close to where i live,Keynsham track is smaller, but it is a complete circuit so you can race laps around it,plus theres a big grass field aswell for bashing if there are too many bikes on the track.,Longwell green track is bigger ,alot bigger jumps but gets very busy on weekends,and if its been wet the track fills up with deep puddles.and Whitchchurch airfield i used to fly model planes and Helis there it a vast open space of feilds/runway/and grass mounds.I stoped flying there due to them building a new hospital there.
