The Absolutely, True Story... by Willo Davis Roberts

I didn't like this book because it was BORING! It's about a sister and brother who go on a trip to the Yellow Stone Park with there New Neighbors, who they just met the Rupes. The Rupes are more feisty than Alison (the sister) and Lewis ( the brother) thought! Alison had offered to babysit the Rupes little kids,but on the way to YellowStone it turned out that she had to watch them every single second, more than she could take! The little kids were very active so Lewis had to help her when he could. Also Mr. Rupe is a horrible driver with a mobile home that was as big as the one they had! How can Lewis and Alison take any more?
