Lillian's Island
(page 145)

Here is a solution from Bo ("The Best Person") submitted in October 2013.

I got 4 because she lives in the middle of the island, and there are North, South, East, and West beaches. I added up how many times she walked which was 6. 12/6=2. The diameter is 2 straight lines connected so 2+2=4. That is the diameter.

Thanks, Bo! So, campers, what do you think of Bo's solution? The thing I wonder about is how Bo dealt with the times when she walks ALONG the beach. What does that path look like? Straight or curved?
