(A) Dan and Sammy cannot believe that they have to move away from Florida. Florida is so awesome! They can play outside all day long – every day. It is almost always warm and sunny, and all of their friends live there. What will they do without Brendan, Bailey, John, Alexis, and Brian? They will never have such great friends again. Never!

(B) However, Dan and Sammy are very excited for their dad. He has a great new job. The only problem is that the job is in New Hampshire. Sammy was not even sure where this state was located. After learning that it is way up north near Canada, both boys did get a little excited about playing in the snow. Sammy has always wanted to learn to ski, and Dan thinks playing ice hockey sounds like fun.

(C) Dan and Sammy also like the location of New Hampshire. It is between Maine and Vermont and not far from Boston, Massachusetts. Quebec, Canada, borders this state on the north. Neither of the boys has ever visited this part of the country, so they are now looking forward to exploring a new area. If only their friends could come with them! Their parents have promised that they can visit their old friends over spring break and even go to Disney World. The boys think that moving to New Hampshire will not be so bad after all.
