Thank you once again for all your suggestions. I spent last Wednesday (my final day in Manchester) making as much use of them as possible! I started off with a NatEx coach to Chadderton, as recommended by Google Maps. At £1.80 for the 17 minute journey it is very good value, although the driver was a bit bemused as to why I was making such a short journey on an express coach service. I then took the 59 into Oldham, my first target destination. Here I was able to pick up the 350 towards Ashton. I rode the 350 for its entire 75 minute end to end journey, enjoying the fabulous views and some very tight roads in some areas. At Ashton I took the 389 to Hyde, wandering around the houses somewhat, mainly because the bus was a Marshall bodied Dart that I fancied a ride on. At Hyde I took advantage of the GMPTE travel shop, purchasing a young persons coachcard and my coach tickets home, before heading to Glossop on the 341. Here there were more great countryside views, interspersed with housing estates and wasteland, all of which was interesting for different reasons. I got off in Simmondley to change onto the 394, using the only 394 of the day to serve that area of Glossop. I got off somewhere between Marple and Stepping Hill to catch the return service to Glossop, which was running two minutes early when I boarded. We picked up just one person on our way back to Glossop, and the service got progressively earlier. I arrived in Glossop earlier than I had planned, but too late to do another journey. As a result I took the Stagecoach 236 to the Gun Inn in Hollingsworth, where my National Express coach was to pick me up. The coach arrived around 10 minutes late, and I ended my exploration of Manchester with fantastic views from the very front of the coach during the journey through Crowden and Stocksbridge into Sheffield.
Still on my particular to do list are the 951, which I have never managed to travel on (although I have been aware of it for ages because it appears in the Peak District bus timetable book produced by Derbyshire County Council) and the 304, which runs so infrequently I couldnt fit it in.
