In Cambridge, there’s a scenic walk along the River Cam which features “The Backs”. It’s a reference to the “back gates” of various colleges and many times includes a vista of VERY green lawns, and possibly punters on the river, before any building rises from the horizon. My morning stroll into town was along The Backs and it was quite appealing, although muddy in places and overgrown in others. Students can enter from this side but not pedestrians and some colleges even had security guards monitoring the passing of people. I found out later that you’re not allowed to walk on the vast lawns and it’s clear there’s an enormous budget for fertilizer, weed killer, and riding mowers!
