...another bi-plane....

   While I was working in the yard I heard what I thought was another crop duster of the sort that I had seen two days ago.  Well, it was another bi-plane low enough that I could see the pilot and another small plane following it as an escort.  Tried to find an image that was similar on the web but couldn't.  The wings on this one were much longer and they were tapered and a bit pointy at the tips.  It was so surprising to see the two planes.  It made me think back to the time when I was about five and I saw a dirigible.  Not too many people around that can claim to have seen one of those large blimps.
