I really regret not taking photos on certain trips because I've had to go back and write down itineraries after the fact to remember what I actually did. No, I don't have a horrible memory, I just do a lot and care to remember the sequence. It's fun to put the pieces together just off memory, but if I miss something, I won't even be sure I forgot it.
That's just me. A photo only takes a second so I guess maybe I'm just young and used to the idea of snapping a shot of things I like. My photo albums are a tangible memory that I'm just proud to have and look through.
