BPF,
I believe that the forum has been shut down - why, I do not know. I asked the same question as you over at AvCanada a few days back - you could try asking further there.

How's the season going? We started off strongly, but it's been damp & cold for the last few days, so not much action. Had a few of your ducks here last weekend - I believe that a good time was had by all.
