I also packed the girls clothes. That was a task I dreaded. We had planned on packing each of them into a regular "school size" LL Bean backpack. How would I ever get everything they would need for 6 months into such a small bag? Well, I laid it all out the bed -- the have-to-go's and the I'd-like-to-gos. And I piled it up into two piles, one for each girl. And I stuffed it in. And it all fit!!!! Yes, other than a rain jacket, fleece, and pair of hiking shoes for each (which are going into a mountain bag with the same for me), all that I wanted to take for them fit in the little bags! YEAH! I did realize that I left their two new suities (aka bathing suits), each, at the cabin. HOW??? I went over that place a dozen times. We'll live. They have plenty of others.
Gregg and I are still waging battles over the box of books (I need books, he wants to reduce weight on Elsie's shocks). Stay tuned (or not, I'll win).
I don't think this is a bad pile of luggage for a family of four on a six-month adventure! (Of course, it's just the clothes...)
