I filled a number of notebooks last summer. I have a rather terrible memory, so I like to jot down as much as possible. Lest I forget about a bizarre incident with (for instance) a particular junky, I have but to flip back in time and I'll be reminded.
Here's my favorite page from the books; the mark in the corner is cherry dip. The notebooks, like my clothes, saw their fair share of "misplaced" ice cream and toppings.
