Thanks to both of you for your information, right now we are in Alabama and have
two weeks to make the border, that should give us the time to travel slowly
to Progresso, we don't tow a car so we will check out the campsites and see if
there is a shuttle as you suggested Texasrver, at least now we know we don't
have to fly up to Canada this time, Mexico seems a nice place for a day trip and possibly longer, I have to add this website has been a great source of information about campsites, much more honest and better description than any books we have read, we will continue to use it and post anything we come across on our travels.
