Like we did in 2014, in 2013, and in 2012, bob and I made simultaneous attempts at Theme I: Buses, subtheme (c) (get on the first bus that comes along, stay on for n stops, get off, repeat), starting from the same stop, with me taking n=5 and him taking n=6.
In 2012 I ended up in Cheam, which is a few miles southwest of Croydon out towards where London stops being London; in 2013 I ended up in Putney, which is several miles northwest of Croydon and very nearly on the other side of the Thames; and in 2014 I actually crossed the Thames into north London. Unfortunately 2016 was much less exciting.
It was so unexciting, in fact, that I can't actually bring myself to do a full writeup. My buses took me along a road that I'm thoroughly familiar with, out to a bland shopping mall, then (thanks to a one-way loop with a stop served by buses in both directions) all the way back along the same route to my starting point, then along residential streets to Crystal Palace (a 9-minute train ride from my house), then through Sydenham (a 12-minute train ride from my house, and a place where I spent an entire day the other week; indeed, one of my stops was directly opposite the cafe I had lunch in), and finally terminated at Elmers End, which is a place that has nothing in it aside from a direct tram back to my starting point. Four hours, to get basically nowhere.
