I've read at least two collections that include this story (Angels and Visitations and Smoke and Mirrors) but it hadn't particularly lingered in my memory. Now it definitely will, as Colleen Doran's intense and detailed illustrations bring it to life - a brief tale about growing up and how it's not all it's cracked up to be, combined with a monster under the bridge. (Ah, but who is really the monster?) She successfully catches the narrator as a boy, a teenager and a grown man, with the changes of time to the physical and personal landscape around him. It's a grim story rather than a happy one, and Colleen Doran makes it all the more vivid. You can get it here.
This was my top unread English-language comic. Next on that pile is Will Supervillains Be on the Final?: Liberty Vocational Volume 1, by Naomi Novik and Yishan Li.
