articles still OK

practice this afternoon went OK.

1. all metal. 6 unscented and one scented. worked the whole pile, brought back the scented within minimal fuss.
2. 5 metal + 3 leather, + scented leather. worked pile briefly, found and retrieved scented.
3. 5 metal + 3 leather, + scented metal (in the middle). Bo went out eagerly and worked the pile really hard, going round it 3 times, scenting hard, and kept forgetting to go to the center. He did not just pick up a leather one, so I finally went and pointed out the one in the middle. he picked it up and brought it and we had a party.
   

I think this might be starting to work?!?!?!
