The train is the best, pick one that goes all the way to kilarney direct otherwise you may have to get off in Mallow, you don't want to do that<shiver>. Then see if you can link up with the bus that goes to Glenbeigh from the train station. From the looks of things there are alot of lifts going so try them first then in a next week anyone without a lift post up, get together as a group and go down on the 28th.
I plan to drive down from home, home being just outside Carlow town arse end of laois. I'l be leaving early enough on the 28th that if anyone wants a lift from me they will have to travel down either the night of the 27th or get an early bus to Carlow on the 28th. But there is a big but my travel plans are directly related to my thesis plans so if I'm not finished I will not be going on the 28th or maybe at all. So I will not be offering a lift until at least the 18th of december.
