david was partially placated when it was mentioned that most of the track would be fenced in , and i finally won him over when i said that he could have as many new cctv cameras as he wanted , covering the whole track , and all fitted with motion detectors , although i did draw the line at electrifying the fences , and patrolling dogs , but it turned out that chalkie was the easiest one of all to please , i just promised him a larger chicken coop ( apparently they are modulated , so it is a relatively easy operation ) , and a full time assistant signalman , and beryl was already busy pricking out her fuchsias .
