Two and a half weeks, three flat tires and about 1,000 miles later, Nate Diskint and Caitlin Keating are well on their way to traveling across the country – on bike.

The two rising seniors left from Annapolis, Md. June 26 with a plan to cycle to San Francisco. Biking an average of 80 miles a day, they will have biked about 3,000 miles by the end of the summer.

Keating said past summer jobs as interns and researchers left the pair wanting more from their summer break.

“We’re both going into our senior year and we’ve been doing a lot of academic work for the past three years and four years before that,” Keating said. “It’s been great to do something we can enjoy every aspect of.”

They are documenting their trip on their blog, “San Francisco or Bust.”

Through the blog, readers can donate money to Common Good City Farm, a non-profit organization Diskint and Keating support. The organization is centered in D.C. and helps grow organic food and educate low-income communities in the area on eating healthily.

Farm manager Kate Lee, 30, said the benefit of Diskint and Keating’s trip is two-fold – they are both providing financial support and raising awareness for the organization.

When they are not staying on farms, the two have been staying with other cyclists they meet through Warmshowers.org, a site that connects travelers looking for a place to stay.

“We’ve had really gracious hosts who have been really interested in our story,” Diskint said.

Both Diskint and Keating, who are from New Jersey, said they have enjoyed experiencing new and unfamiliar areas of the country.

“It’s been really eye-opening,” said Keating. “It’s just interesting to see how people live besides the people you’re normally around.”
