The Experience Journal by Hanna Yoon forces you to stop and take inventory of your surroundings, so that you can look back and better remember your experiences there.
On one side, the journal has blank spaces that ask you for details like the date, weather, the location you visited and if there was any particular occasion that went with it. The journal also has spots for you to note how the place makes you feel and even a spot to describe the quality of the place's washrooms. As well as being able to jot down a bunch of little notes, the journal's pages also have some space for sketching details, floorplans and any other impressions you'd like to capture.
Yoon's Experience Journals recently went up for crowdfunding on Kickstarter and concluded on April 24th with wildly successful results.
