Diesel spillages are horrible, the unseen hazard especially in the wet, dark days that are now upon us.
Glad to hear you are ok.
Be aware of the danger on roundabouts and long curves. Lorry drivers always seem to fill up to the brink, possibly because of pressure from employers or deadlines! Apt word when cyclists and spillages meet.
If a pothole get a picture and location and report it, if enough do complain it may get sorted. Make a mental note in your head of the spot and be ready for it.
There may be a future ride when you have no option but to ride across it again. It wakes you up doesn't it.
Take care, be aware.
