I had a lovely ride back this evening. Stopped at Didcot Station to adjust the boom a bit (changed to Look pedals recently) and said Hi to an Aussie on a 24" yike, rolled on through South Oxfordshire on a warm windless evening with the roads almost to myself, and saw and heard several owls and bats. And nobody overtook me just before my favourite downhil, so I was able to blast down it at speeds in excess of R17. Wheeeeee!

Ah, I see:
R17: "Spontaneously flammable in air"
"R is a velocity measure, defined as a reasonable speed of travel that is consistent with health, mental wellbeing and not being more than say five minutes late. [...] R17 is not a fixed velocity, but it is clearly far too fast." D. Adams.

As opposed to the classic "R57: Toxic to bees". Always amuses me that the humble bee (no, not a typo for 'bumble bee'😉 gets an MSDS risk phrase all to itself! R54 is apparently "toxic to flora", though I don't know what effect it has on other brands of sunflower spread. I'll get me coat....
