I treated myself to a deliciously sexy bicycle bell at the weekend. 
I've been resisting temptation since the day I bought the bike, but I couldn't justify holding out a moment longer. 
It has a TING! so crisp and sharp that even a microwave oven would be envious. The sound carries vast distances and turns heads in the fog.
Exactly what I needed!
Riding in to work this morning was very dark and rainy. Walking people held umbrellas so that they could see about 2 metres of ground ahead and nothing at all above. Dog-walking people were making sure their charges didn't jump into the fast-flowing river in pursuit of ducks. One of those vast mobile crane trucks with an orange flashing light at each corner chose to stop to check where it was supposed to be right across the pedestrian/cycle route crossing.
I didn't dare go round the front and I didn't dare go round the back, so I TING!ed, and blow-me-down, hefty truck moved forward off the crossing.

*Ah! The wonderful Syd Barrett, born just one year and two days before Mr David Bowie I see.
I'd love to witness a Syd Barrett birthday jam!
