So what time(s) is this all going down? It sounds like an "all day" event but I know that I will have soccer games with the kids that morning, so I wouldn't be able to get there until maybe 3pm. If things are going to be happening late afternoon/evening I'm sure the family would like to come out.
Do not eat any of it raw or boiled at all with water, but rather roasted with fire. Exodus 12:9
