Not just folks in Texas.
Here in California, I've already received three phone calls from scammers soliciting funds for victims. How do I know they are scams? They all wanted me to use a pre-paid card to donate. One offered to transfer the money for me to save me the trouble of getting a pre-paid card, all I had to do was give them my account number.
Don't fall for scams, folks. If you want to help, initiate the call yourself, and only go through a recognized relief agency.
