Hero had A[img]/images/graemlins/heart.gif[/img] A[img]/images/graemlins/club.gif[/img] (two pair, Aces and Nines) and LOST (-$6.50)

Aside from the river (especially because I was all-in before that and trips are more likely to show up than quads) did I play this poorly? Bit unsure how I could have done this differently. Since hindsight is 20/20 I guess I could say fold pre-flop, but seriously, it wasn't much more to call the re-raise on the flop, especially relative to what I had in there and the pot.
