After giving the squash a bath, hack it to bits. Its harder then it looks, this is one mighty squash. Remove the seeds from the bell at the bottom, an ice cream scoop works well.
The next step is to steam the squash. We got out our very large, 20 quart, beer brewing pot. Put a veggie steaming basket or a stainless steel colander at the bottom, add a couple of inches of water and pack the squash in. This one filled the entire pot. We cooked it for 30 minutes (a smaller squash should cook in half the time) and it was really nice and mushy. Peel off the skins. If your squash is watery, let it sit in a colander for a few hours to drain.

After we got to this point, we had to take a break and our squash turned into a giant squashsicle. Hopefully, it will turn into pie soon. If you must know, the story ends with pureeing, seasoning, making pie crust, baking and eating.
