North Salt Lake, Utah, residents Joshua Keeler, Joey Stocking and Adam Gatherum left from Vermont Sunday to begin their mega road trip, the Star Tribune reported Monday.

The Minneapolis newspaper reported the three men, ages 20-25, had made it to Alabama, their 17th state, by Monday morning.

"This route has been checked and rechecked for shorter possibilities and triple checked to be sure that all 48 states are included," Keeler wrote on greatamericanroadtrip.us.

The adventurers are tooling about 7,500 miles across the country in a 2005 Toyota Scion xB because "it is roomy and gets good gas mileage," Keeler wrote.

The men said they are going to use the help of a global positioning system and AAA maps to make sure they don't get lost along the way.
