This has fondly reminded me of the time when i found myself in one part of London (near Hyde park) and wanting to get to another, (near London Bridge) to meet a friend for some drinks.
Having decided that taking the tube would get me there far too early, and have me waiting around like a lemon looking for some Gin, i decided to walk it.
Start and end points plugged into google maps, music on, headphones in, phone back in pocket and away i went. Due to the helpful voice in my head telling me to 'turn left up this road' in 'x feet'I didn't have to focus on my phone so was able to relax and enjoy the walk, and didn't get lost.
Arrived exactly when i needed to, and went to the pub.
