Passed through the Westlink and the usual massive queues today.

I nearly killed an unlit bike rider last night.

Under the rules of the road, you use your horn to warn of danger, so I plan to blow my horn whenever I see one. Enough horns will alert the gardaí to the law breaker. - Michael O'Malley, Dublin
