Bringing meat home from a trip

I'll be heading out to Junction in a few weeks to hunt at my brother in laws place for the weekend. My question is, do i have to keep the meat quartered etc until I arrive home, or can I process at his house there before I return home?

I would say that his house is your final destination and that you could process there. This is exactly what we in our family.

I agree. You'll be fine.
