Prompted by yet another CF parking thread on the go, and the numerous shouts of 'buy a penguin bollard', it occurs to be me that whilst buying a bollard is a doddle, £35 and one arrives the next day on Amazon, for example. How the dickens to you actually install one? I find it hard enough to drill into the wall to put up shelves, never mind into concrete or tarmac.
Perhaps bollards aren't so simple after all?
