Suggestions for family games while RVing/Camping

I picked up a Boy Scout Handbook at a garage sale. It contains a lot of things to do and see when camping. It has pages showing how to identify plants & trees, insects, animal tracks and scat plus handy stuff like fire starting, knots, map reading, cooking, survival techniques...etc.

We always have the kids research the areas we are going to to find places of interest and they list what they want to see and we go see as many as we can.
