Overgrown paths and prats in cars.

as the title says, nettle stings on steep loose climbs are never good and idiots who think they can overtake you in their cars on narrow lanes at speed and then the ones who dare not pass you when you're toddling along happily at 12mph enjoying the views on a lane that's wide enough to overtake you in a bloody tank! great ride though, just a shame about the prats.
