Definitely an adult party, Scatterbrains. No one under 21 allowed. So yeah, I think the sausage is a definite must...though I may surprise my hubby by adding that at the last minute (he'll laugh so hard!).

I think we'll have to have a meat head too - I was looking over that post the other day and telling hubby about it, and he thought that was a great idea. French bread for the thighs, definately! I think I can make a bruchetta "loaf" so there will be red tomato filling between pre-cut slices. Perfect!
Thanks for all the links - I'll check out those fleshworms and more jello molds. I found the Alton Brown Panna Cotta brain - that is definitely going on our dessert list (I love panna cotta!). I need to find that bleeding heart recipe too...
I'll post pictures both of our "trial run" this summer (just to try it out) and the real deal for our party next fall.
We actually start on the inside of our house in September, and don't even decorate the yard until two weeks before Halloween. Our party is the weekend before Halloween every year (I think this is our 6th year), so the adults can come and have a good time, and then they can bring their kids around on Halloween night (we don't allow kids in the house for many reasons, but we sit out in the yard for trick-or-treaters). We're childless by choice, so the party is for us, and Halloween night we enjoy seeing all the kids come by in constume (and chatting with their parents).
Thanks again for all the great ideas...anything else people think of is certainly welcome!
