I just found this in the TDR issue #58 and would like to share it with everybody. It's a book called "The ultimate travelers exit guide." We had, at one time, a book called "Exit Authority" which we liked because you could follow a route from one end to the other whereas the "Next Exit" required you to change pages from state to state. This book is laid out like that and that means the DW can follow it a lot easier. But, see for yourself. The web site is www.milebymileplus.com. I hope this will help somebody. OP
