as for your kids. They can leave postcards with their classmates, if you prepay the postage, and pre address them, they may actually get quite a few back. make a scrap book of their fav places in your old town and then go to the tourism info of your new town and look for places you want to check out like mc d or an icecream parlor etc. gives them something to look forward to.
