When my children were growing up I wanted them to see as much of the USA and Canada as possible. We started out with a maximum of three weeks in the summer and we were tent camping. We left late afternoon of the first day of my vacation and drove through the night the first night out and the last night going home. By using seven days to go and come, we had two weeks to sight-see. It is amazing how much we could cram into that time. When my third son was born, I took a considerable cut in pay to contract with a school system (I was a child psychologist) so that I could have six weeks off in the summer. Wow! What we could do with six weeks is incredible. Now, we are retired and go with the flow. We spent 90 days on our last trip to Alaska and it was not nearly enough. This year we plan to stay "as long as it takes". My advice? Do what you can when you can. You will never regret one minute of it. lizzie
