I am staying in Manchester for the next few days and I would be grateful for some recommendations of "interesting" bus routes. By interesting I mean ones which either have interesting vehicle allocations - such as minibuses, coaches or older vehicles, take strange routes all round the houses etc or routes which go quite rural. In particular the ones that run very infrequently via minor rural roads etc are quite interesting to me. I don't particularly enjoy sitting in traffic on a standard urban bus! Any suggestions are welcomed, thank you in advance.
