Listening to the debate on the @PatKennyNT about car parks etc at the airport. Why not bring back the Aer DART? It was a bus service that ran every 15 mins from Howth Junction to @DublinAirport . Its about 15-20min trip and would offer another option to get there.

A temporary 3km long cycleway should not be making national news. It should be a very easy win. If the easy projects are so hard to deliver how do we deliver the bigger harder changes - it is a climate emergency @GalwayCycling should be very proud of the work they did & are doing
