They did not travel well outside of California. When they were in Jacksonville a year or two ago. the stadium was full of them. ALSO.....It's like they pop out of thin air. That game here in Jacksonville....The afternoon before, I did some running around Downtown (Very close to the stadium) and did not see ONE Niners fan. I even was by the Riverwalk, a popular tourist thing. When the Packers are here, it's nothing to see Packers fans.
I'm afraid we better get used to it because they are building a good / strong team in SF.
