Kara Swisher, veteran newspaper reporter with the Washington Post and the Wall Street Journal, now co-head of Dow Jones' AllThingsD, knows how to get the  her interviewees chat. 

But she runs into a tough subject with her Mom in this roadside interview at a Chevron station.  It's pretty funny when Kara needles her about Twitter (45 seconds in).

She put together this little road trip video of drive from LA to Carlsbad where the AllThingsD conference begins tomorrow night. 

Also, in the video is her colleague and partner AllThingsD Walt Mossberg.

I will be at the conference tomorrow to cover for Beet.TV
