After just one column each from your new Inside Trackers, we already have some common ground and a new scientific formula, it seems. AB+BC=607. Isn't it a small world? I might unwittingly have met my fellow Buses contributor when we were both in short trousers, somewhere around Hayes End turning circle. If I had the time to dig through the output of my Box Brownie [does that need explaining, Mr Editor?] there might just be a picture of a 607 trolleybus with young BC looking lovingly at it. Ah well, as he says, us oldies can so easily regress to childhood.
