Thank you for the responses, I did not expect such thoughtful replies and I really appreciate seeing the argument over whether flying must be 'in your blood' or not to become a pilot.
I think I may have recieved an injection, thanks to YouTube. Make fun of me for this but I've been watching some videos of African bush pilots and I think I'm hooked. When I go back to school next month I'm going to take a loan out (I'm fortunate enough to have no debt from college) and go for my PPL. If I change my mind after that, well its a few thousand dollar mistake but I won't be much worse off than other grads. If I don't, then I'm on my way.
