If you're planning on bingeing your way through an elaborate St. Patrick's Day crawl, you're clearly not responsible enough to plan an elaborate St. Patrick's Day crawl. Tomorrow, let PubWalk pick up the slack.
Harnessing the power of CitySearch/GMap, PW lets you quickly construct a shareable "pub walk" -- a term the site's spin-doctor creators invented by adding a dash of unlikely respectability to "bar crawl". Just pick your city/neighborhood, and bar markers'll flood the screen; browse all, or sort by type, like "Dive", "Billiards", or "Romantic" (for people who've always wanted to puke in someone's roses while wearing a leprechaun hat); click individual boozeries for details, and if you dig them, add them to your itinerary. Destinations are easy to re-order, and PW'll continually estimate walk time and trip duration, assuming a half-hour at each joint -- because as everyone knows, on drinking holidays, the fun's in being wretchedly anal about punctuality.
Once assembled, you can email your walk out or embed it on a web page, plus the mapped route's mobile compatible -- because no matter the pre-planning, once things get going, you're barely responsible enough to remember your "Blow Me, I'm Irish" shirt.
