Been with Adsense for few hours.Same ad being displayed?

I only see the katrina ad when my site is for offroading

Is this normal for AdSense to put a generic ad for the first few hours? I'm getting the Hurricane Katrina add when my site is about Dirt bikes?thx!

Yes, very normal. You should get basic targeting within a day, perfect within a couple of weeks.
