Climbing Logbook

I saw this logbook advertised and thought it’s a good idea for any climber – especially if you climb in different areas.. Don’t know if you need to spend $13. Maybe just a notebook listing where you were, what the weather was, who you climbed with, what routes you did, additional beta, and gear you used, would be sufficient. I used to just write info on the sides of my guide books. But years (weeks?) later, it is fun to review where you’ve been and what you’ve done
