So my father (tried to) raise me on the ABC's... Always Bring Cash... He was not a fan of credit and credit cards. With traveling, and rewards programs, there are a number of various Credit Cards people hold, and some for just the rewards program as well.
I have a RC card through BOA (have points saved and never have used them...yet), but I'm curious to some other cards that people may have and why/what are the rewards programs and are they worth your time. Southwest sends me something at least once or twice a week on their card, and I have seen numerous people have them.
