June challenge: IIb in Cambridge

[shewhostaples]

Last weekend I had a go at challenge II (b):

II. (b)

Get an A-Z map (or similar) of your city - something that has a grid of squares overlaid on the maps. Choose a page at random, then choose a grid column on that page at random. Start in the square at the top of this column, and travel as far as you can down the page without leaving the column.

I couldn't find my A-Z street atlas, so had to use a city centre map. ( Report, with images )
