Someone told me a few days ago that they read, or saw something on TV, that lightning tends to strike the same area, and that once an spot has been struck it is more likely to strike there again.

The article Lori linked to seems to lend some credence to that. I have no idea where they said they read or heard that, but I'd like to know more about it.

I used to walk the trail on Morro Rock in Sequoia NP when I was young, and recall the signs warning of lightning striking it. I didn't worry much about that when I was on the rock though, I was way too busy praying I didn't fall off of it
