NAIROBI — Excitement built before President Obama's arrival Friday in the country of his father's birth for a two-nation African tour.Kenyan and American flags were hoisted along roads, cleaners scrubbed the asphalt clean, and police relocated homeless families from the routes Obama is likely to take. James Bwire, a Nairobi-based sculptor who designed several billboards to celebrate the president's visit, said he hopes to get close enough to deliver a small bust he crafted of Obama.
