Glad you enjoyed my beloved city, You are right about the glens - probably one of the world's most beautiful spots. I would not want the area to get too commercialized, just keep it as it is. I hear they are starting to build a pub at the Causeway, have they made any headway ?. I hope they don't, the area does not need anything that may attract a rowdy element. Plenty of opubs in Ireland they don't nee done there.
Anyway, glad you enjoyed yourself.
I will be there in may, will have a drink for you. Maybe a soda farl or two.
