For the last few years that I lived in Ireland, a friend and I would grab some "flagons" (two-liter plastic bottles) of cider on St. Paddy's Day. We'd hike the hell away from town and light a campfire beside the river.
There, we could smoke hash, drink, fish, talk, and keep the fire going until late. Most of it was legal the 17th of March is the first day of the fishing season.
It was great. We did that three out of the last four years I was there. Saint Patrick's Day will never again be that good.
