I never thought I'd ever discover anything of practical travel assistance on the trendy Jaunted.com website (www.jaunted.com) designed for social climbers who aspire to travel. But in an unguarded moment -- and alerted to it by a young relative who actually does look at the jaunty Jaunted -- I discovered their recent advice to buy Metro passes in advance of your trip to Washington, D.C. for the inaugural ceremonies and parade on January 20. According to Jaunted, lines to buy Metro tickets for use on January 20 (the only practical way of getting around the city; driving won't work) will snake through the Washington, D.C. metro stations and out onto the sidewalks above and then perhaps for a block-or-so, requiring a lengthy wait. To avoid that, you're advised to buy a MetroRailPass ($7.80 for the day) in advance, online, by going to wmata.com/onlinestore/default.cfm.
