Joe,
I just saw in the headlines where they had a big cave in at San Antonio I think it was. What happened there? There wasn't much about it in the article. Just a picture and a few lines. Guess they couldn't wait to find out as they had to beat the competition to getting the headlines.
Ok, I found the article and it seems the dirt is just sliding.
