Tomorrow, Laura and I drive off to Sun Valley, Idaho for a week of vacationing with my family. Both Mapquest and Yahoo! Maps agree that it’s about 790 miles (give or take). The routes are almost identical, but Mapquest says it will take us 14 hours and 23 minutes and Yahoo! Maps says it will take us 12 hours and 16 minutes. Obviously, Yahoo! expects us to drive much faster. I guess we’ll have to try and oblige.
