My mom's family is from Glenties in County Donegal. I got to spend a week with them. They were so kind and it was neat seeing what their everyday life is like.
If you are asking me, I'd go back in a heart beat. The time surrounding that week I also spent time in Dublin and a few days in Dingle.
We're all friends nowadays pal, you'd be more than welcome. I spend a lot of time in the North myself, the missus is from Belfast.
Every 2 months or so. I was up there for NYE. You should venture down south for a weekend. You'll be safe as houses down here pal, nobody gives a shit down here what side of the fence you're on.
