when there was an earthquake...it was crazy!!!

We were staying at the Horseshoe. My husband was taking his son and his wife to the airport about 8 a.m. and they didn't notice it, at ground level. I was in the hotel tower, and woke up feeling like I was moving...and I was sober! Then I saw the rod that you use to open the drapes was swaying...and I heard the maids out in the hall chattering away, and heard the word "earthquake"!! Luckily for my peace of mind it only lasted for several seconds, and it was over...but it was weird!!!
