Glen,
It was one evening. I have been doing this for a lot of years and that was one of my more productive locations. Normally I can get a couple more species of grebes, a few ruddy ducks and maybe 3 or 4 more species in general in one evening but the weather was a little challenging this time. I think central Michigan would have some pretty productive locations also. I don't get back to that area like I used to but if I do I will let you know and we can see what we can come up with. I would love to see that Petrel that you built a while back.
