Steve and Jo are currently hitchhiking from Argentina to Alaska in aid of Tearfund, where Jo worked for 3 1/2 years.

Tearfund is a wonderful charity, working in around 60 countries, empowering local people to lift themselves out of poverty. For more information, visit www.tearfund.org.

Please help us to support their work by sponsoring us. How about a penny per mile?! We'll leave you to work out the maths...!
