Well, plans changed a bit ;)
I now have three drums and will be hauling them to the site the night before, and cooking everything on-site. We'll hold the pork 'till serving and keep it whole as long as possible before pulling.
Finland has extremely strict health regulations, but as this is a guerilla event held by private citizens, they are not governed as such (but the event is supported by the government). Checked the fire regulations, we are good to go unless we'd have an open pit
I'll be buying around 75 lbs of pork neck for pulled pork and one whole beef neck for pulled beef as well. Let's see how it goes, generally people are not really trying to make money on this day. Many use it as training wheels before eventually going commercial, but I have no plans to do so. Perfectly satisfied to Q as a hobby
