Madam, – Reporting in your paper, of delays experienced by concert goers travelling to the recent AC/DC concert at Punchestown (“AC/DC fans clog roads before gig”, June 29th), suggested that the delays were caused by concert goers alighting prematurely from coaches on the M7. As one of the unfortunate concert goers forced to abandon a Dublin Bus coach in an attempt to reach the venue in time, I cannot imagine what benefit your reporter and AA Roadwatch assume would have accrued to concert goers who chose to walk over five miles to the venue instead of remaining on freely moving buses. People left the buses because the buses were at a standstill on the M7 — the buses were not at a standstill because of the actions of concert goers, but rather due to the lack of any obvious traffic plan. Luckily the excellent concert more than made up for the torrid journey. – Yours, etc,
