"That's right because this gives the people who actually live in a state/province/country to showcase their \"home\" area. If I picked someone from South Carolina and they did North Carolina and South Carolina caches, than anyone who volunteered from North Carolina wouldn't be picked down the road because it was already \"showcased\". That is why I said no vacation caches, yes, I really meant that. The only thing I can suggest is if someone does not agree with the terms of the \"CHALLENGE\" is to not volunteer. \n"
