There i was flying down the hill at 27mph when i hit the unsigned roadworks trench. The bottle flew out of the cage and the rear light flew off as well! When these things happen i tend to do a stop asap rather than an emergency one as my safety is more important than a bottle. Anyway, i turned round to retrieve if possible the lost items, and as usual you watch oncoming cars pass the things by inches, then it happens! It's always the third car that hits it! Luckily my bottle was full so it broke the crush although it took some reshaping, but unfortunately as i went to retrieve the rear light a car came from the side road and went right over it!
