Thanks everyone. I'll be in the area of a couple of those places over the weekend and i'll report back. If no luck, i need a good excuse to travel further afoot next week anyway.

Thanks for all of your (no doubt expert!) comments. I can't feel ok about serving it to guests, so i went out and bought another. I'll roast them both, serve the new one to the guests, and cook the other more well-done to slice it up (maybe freeze some) to eat myself to less exacting standards.

Guess i'll be eating lamb for a few weeks. Lamb soup, lamb stew, lamb ice cream...

Frozen like a rock. 4-1/2 lbs.
