Another marathon??

Well, I've been reading my Runnersworld magazine and am thinking of running another marathon. I cant decide whether to run Little Rock, AR/ Las Vegas, NV/ or the Rock-n-Roll marathon in San Francisco...? Little Rock has the largest finishers medal in the US, so that is a big selling point! ;) Anyone been to Little Rock or San Francisco? I've been to Vegas, but running down the strip would be fun. This will be the first year that they have a marathon that runs down the strip. It is on Dec. 4th.
