What's so good about it? Certainly not throwing rotten food at people carrying their crucifixion crosses up the hill, although it is pretty easy to get caught up in the mob mentality. And if you're the guy that has to carry the cross? Sheesh.
On the other hand, if you adhere to the no meat during Lent policy, the one I made mention of in an earlier post, you have a great excuse to eat fish and chips. Unfortunately, the best fish and chips are all the way over in Galway, so I'll probably just have a turkey club. Buen Provecho.
