I've got no issue cooking the spit (except that it's broken and I need to fix it).
I haven't thought about Sunday morning. I'm open to suggestions. There's a few cafes here that do a very good breakfast.
It's not going to get dark until nearly 8PM, so dinner can be fairly relaxed. The BBQ's at the site are wood fired, so i'll need time to get them going anyway. I'll provide the lamb, if someone could bring sausages, that'd be good.
I'll be at the site by 3PM in order to have the spit going. People will be welcome to join me at any time after that. The roast will be ready by 6PM. It'll take you 2.5 hours from Cragieburn to Wangaratta with no stops. If it takes you longer, you're driving too slowly.
All of this is assuming, of course, it's not going to be pissing down rain.
