Sounds like you had an exceptional duck hunt over the border, good for you! Cans and Redheads, Wow! Is the process for bringing ducks back across as tough as the few walleyes and lakers I did a few years ago? (It was bad enough that I haven't been back to fish since.)
Moreover, I'd think the Canucks would just about go ballistic when they saw you coming north with that big Parker 10 of yours, so how does all of that work? Just flying my 10 to Minnesota every year is something of a trial (the ticketing/ baggage folks almost always make some sort of snarky comment and try to gig me another $50 for the extra weight)and god-forbid you have any shells that aren't perfectly boxed (partial boxes seem to be an anathema to them), and fully identified. Then, after the almost proctoscopic examination my gear, and with half a roll of TSA-security tape wrapped around them, only 2-boxes of shells are allowed. I can't imagine that Canada makes the transit process any easier? I would think that our socialist neighbors to the north would have deemed the 10 a destructive device by now. Do you have a good source of supply north of the border?
Also, how do you prep your ducks for the table? Do you pluck or breast and do you have any particularly sucessful recipes you would be willing to pass along?
