It doesn't matter if you are visiting the Grand Canyon or the town next door, but 30 years from now you are going to look back fondly on these memories. That is if you can remember them. The human brain takes in so much information on a daily basis that its easy forget some things down the road. Soon, you can't remember if you went to the antique store before or after that amazing lunch or if the place you got that tea cup was the same place that sold those great scones.
If you want to keep this kind of thing from happening, then you need to create your own travel book while its fresh in your mind. I am not talking about some professionally written book that you can publish. I mean a journal filled with your daily insights and events that you can look back on.
The easiest thing to do is purchase a blank journal and at the end of the day before you go bed, sit down and take an hour to jot down the things that were memorable for that day. Do this for each day and pretty soon, you have a resource that you can look back on if the details ever get fuzzy. This is also perfect for children who either weren't born or were too small to remember the trip.
