Only Ireland can celebrate Maewyn Succat, a.k.a. St. Patty, better than Boston. And besides just being gross, kissing John Harvard's toe doesn't quite carry the cache of kissing the Blarney Stone. Luckily (no pun intended), computer technology can help: start your St. Patrick's Day observance by exploring a next-best computer simulated Blarney-smooching experience at the Top O' the Morning Web site in the St. Patrick's Day Webring. It's hygenic and may bring good luck! http://www.geocities.com/Heartland/Fields/2142/ StPat.html. FREE.
