When you publish the book, please include maps showing the locations of
each shot. That's not too much to ask.

Would you like me to make a reservation for you at the hotels I stayed in?
Actually I've addressed the situation you mentioned for my own purposes.
Starting this year, I've geo-tagged every photo I've taken. That means that
encoded in the EXIF data is the precise lat/lon coordinates I was standing
in when I took the shot. The software I use to do this will export the
geo-tag data as waypoints that can be used in Garmin's MapSource software.
This way, when I look at a photo 10 years from now, when I'm even more old
and feeble than I am now, I won't have to remember where I took the shot.
All I have to do is look at the EXIF data and it's permanently written right
there. Cool stuff.
