How to get from Boston to San Francisco? Flying is perhaps the most practical way to get from one coast to the other. Buses and trains work too. And the cross-country road trip has become a staple of American culture, right up there with motherhood and apple pie. But the idea of a cross-country trek on foot hasn’t quite the same universal appeal just yet. In fact, the list of people who have walked across the United States is only a couple dozen names long.

Walking across the country takes time, money and physical ability. It takes a lot of planning too. What to carry? Where to sleep? Should I bring a gun? Figuring out a route isn’t as simple as booking a ticket on Expedia and hailing a cab from the airport. There’s no Interstate Highway System for pedestrians, so each attempt to cross the nation on foot carves a different path. Doris Haddock, the 89-year-old activist affectionately known as “Granny D,” walked from Pasadena to Washington DC in 1999, while 30 year-old civil engineer Matt Green, walked from Rockaway Beach, New York to Rockaway Beach, Oregon. And while there are plenty of books and websites about driving from sea to shining sea, there’s not a whole lot of literature about how to walk across the country.

That’s where Evan and Jade come in. The couple is hoping to make walking from coast-to-coast much easier by blazing a trail and producing a guide book called “The Adventure Access Trail: How to Walk Across America.”

A cross-country walk is difficult enough without having to worry about every last detail or unknown variable. The Adventure Access Trail enables adventurers to be informed about these logistical aspects so that they can focus on the fun and interesting challenges of walking across America. – Evan & Jade

The book will be based on their 3,400-mile journey across the country which begins in Boston on July 1. Their goal is to reach San Francisco by Christmas. In order to hit that target, they’ve got to average about 20 miles per day. Along the way they’ll place stickers marking the trail, and they’ll even rate each checkpoint based on climate, walkability, provisions, mobile phone and Internet service and how friendly the locals are.

Evan and Jade are raising funds for their guidebook on Kickstarter, where, depending on pledge level, backers can pre-order a signed copy of the guidebook or even lay claim to a checkpoint along the route. For updates during their journey, follow @adventureaccess on Twitter.
