Catalpa pods

My dad used to talk about trying to smoke catalpa pods when he was a kid.  I was never really sure what a catalpa tree looked like.  Two or three weeks ago I passed this tree down the road from us and it had orchid- like blooms.  In searching online, I found that it was a catalpa tree.  On my walk today, I see that it now has pods. You can see a couple of pods near the top of this picture.  Good to know what a catalpa tree and its pods look like.
