Asking for the Father's Blessing?

Personally, I don't see it as much of an option but a necessity but I've always been old school. I asked my lady's father over the phone because 600 miles is a bit much; I do wish I had done so in person though. I have yet to pop the question as I need to ask her grandfather (mother's side and was pretty much her father growing up), save up some more money, and wait for the right moment.

Her father and I are cool so he totally supported it. If he didn't approve I'm not sure what I would have done; either do it anyways, or work to butter him up until he approved I suppose
