No worries on the late reply, I wouldn't have made the monster I have if it weren't for you!
Anyway since I couldn't get any real pumpkin I went with the pie filling and put in 9 cans. I made a few changes to your recipe, such as cutting the hops back a bit and upping the fermentables. I added a pound of honey, some molasses and a pound of brown sugar... ok two.

I like making high gravity beers and this one should be impressive. I was contemplating making a starter batch to add some distillers yeast to put it over the top, but if I do that I plan on adding some more spice and vanilla to cover the alcohol. It's bubbling away like it's on a mission so the yeast is still doing it's job, but it wouldn't be the first time the alcohol was more than the yeast could bear in one of my beers. It's been going for almost two weeks now and is still bubbling every couple of seconds.
I was originally concerned with the volume loss with the excessive trub from stuff settling out, but three gallons of boiled water +2.5 gallons and all ingredients fit into my bucket just fine... and it smells amazing

On another note, if I had a "friend" that would like to take a beer, freeze what would freeze and then remove the ice from it would the carbonation still be there? I've told him that it isn't exactly legal but he just doesn't care.
