Appears your iPads are trying to tell you something, like move to Texas.
I assume the iPads are wifi only. Look at this link about Location Services iOS 7: Understanding Location Services
Location on wifi devices is approximate, however, it should not be that far off. Cellular iPads have GPS and location services is very accurate.
Have the iPads been taken to Texas?
Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430
To solve some problems, just follow these simple steps
1. Go to Settings
2. Tap on General
3. Tap on Reset
4. Tap on Reset All Settings
What this effectively does is to reset some of your Settings to factory default. It’s not a complete removal of settings. It removes all of your preferences for Wi-Fi, Bluetooth, Do No Disturb, Notifications, General, Sounds, Brightness & Wallpaper and Privacy. It doesn’t affect your data. All of your email accounts will remain intact, as well as any SMS text or iMessages.
