Ok, this was probably a bit less than a mile from my car as the crow flies (or seagull, in this case), at Sachuset Point NWR in Rhode Island just before Thanksgiving.
I didn't realize that you were a New Englander. Sachuest Point is a great birding spot which (sadly) I'll probably get to less often now that my daughter moved out of the area. I got a lot of first-time shots down there last year, including Harlequins, Pintails, Scoters, and as well as a couple of Owls. I have a hard time getting there in the time of day with good lighting, though. It's right up there with Plum Island and Mt Auburn as the best New England birding spots.
BTW, to stay on topic of the original post, I bought a 5DIII a couple of years ago after giving up on the wait for the 7DII. I wish that I had a 500/600mm lens, but I'm "making due" with a 400 f/5.6 and a Kenko 1.4x teleconverter. I don't see a need to switch over to a 7DII even though my main interests are bird and dragonfly photography (hobby level, not pro). If I didn't have either one, I would probably go with a 7DII, but that is just based on my interests. I do see myself upgrading to the new 100-400 at some point to get the IS and the incredibly short MFD on the new lens.
