Consider yourslef lucky, you could have ended up in a bad place if you were to come between her and her cubs, it would not have gone over as well as it did. But you did the right thing by making yourself appear larger and making enough noise. Bears do not like human interaction. I have had several run ins wiht bears and the best thig to do it not panic, make a ton of noise entering and leaving the woods, and make yourself look big. You may want to invest ins some bear pepper spray or consider carrying a pistol, nothing smaller than a .44 mag. if thats legal for you.
