I agree with above!....I have had my credit card malested to the tune of $40,000 I freaked and shut it down not thinking it was the only card I had to easily buy fuel with! I was excused for the sum but the inconvienience of not having an easy to use card was extremely inconvient! Always carry two cards as stated above, and make sure they both are easily taken all over North America. American Express isn't one of them!
