I'm from the Boston area but thinking about a change of scenery for St. Patrick's Day. In the Irish Pubs of Montreal, is it being celebrated all weekend March 15-16, or mostly on the actual day March 17? I've visited Montreal many times and have heard that the St. Patrick's festivities are not to be missed.  In Cambridge MA and Boston, the pubs are "officially" celebrating on Saturday the 15th, with more tame events planned for Monday the 17th.  Any tips about pubs to visit would be greatly appreciated. Cheers, Jake
