Antarctica.

In our study of the character trait of determination, we have moved (temporarily) from the Olympics to a study of polar expeditions, starting with Antarctica. We read a book on Shackleton's Antarctic shipwreck survival story and have been studying about Antarctic plant and animal life. My youngest son, who has been wishing it would snow more here, has suggested that our next vacation, we go to Antarctica. He has it all planned out. He said "We'll go on a 3 day vacation to Antarctica and since days are 6 months long there, we'll be on vacation for a year and a half!" Good plan!
