Getting out of Addis

Hi,

I'm coming over to Addis for a week with work and was looking to make the most of a free weekend there to see as much as I can.

I'm a big fan of wildlife, sadly I 'm prob too far away from the best reserves, but if anyone can reconmend any fun places to go on the sat and sunday I would appreciate it.   

If no wildlife around then what would you suggest for the weekend??

Thanks,

Guy
