According to reports, the Spanish driver was in Kenya to take part in a New Year's party that was hosted by Flavio Briatore, the managing director for Renault's Formula 1 efforts (sounds suspiciously like your New Year's too, eh?). It seems that while the accident wasn't particularly serious, Alonso, his wife and his brother-in-law needed to postpone their return home until Monday.
Side note: After commenting on this crash, Alonso's manager is again quoted as suggesting that his client has a longstanding interest in getting a shot at the driver's seat for Ferrari, yet Alonso is contracted with Renault through 2010. Hat tip to reader Dan!
