Russ McClintock, a BBC News website reader, documents his trip across the US and Canada.
"On 30 July 2004 I began a bicycle trip from Seattle to New York City.
"After only three flat tyres I arrived at my destination on 18 September.
"My intention was to photograph my experience of the landscape in a way that was as honest and as accurate as possible, this is the result.
"There are no captions, just a note of the location and date I passed through."
