"Family Radio" is what we are referring to. YOu want the US/North American channel plan, so if you buy from eBay or Amazon, beware that you may be wasting your money.
Just go to Walmart, Target, Cabela or Meijer and get a set of 14 or 22 channel radios like these:

Midland® X-Talker XT T10 Radio : Cabela's

We will use Channel 10 around the Lodge so be monitoring that when you arrive. Sub Code "None" or "00".
On the runs, your leader will tell you what channel to use.
