Tourism collectibles are 28 pre-outbreak brochures, menus, posters, signs and postcards. Most sit inside diners, motels, gas stations and visitor centers, so search buildings as you pass.
They paint the area as it was just before the outbreak, with festivals, ski trips, hot springs and fishing rules. One Iron Butte memo about virus samples is a nod to Bend Studio's Syphon Filter games.
Collectibles
Days Gone has nine collectible sets, from character keepsakes and roadside plaques to NERO files, Ripper sermons and wild plants. They are spread over all six regions and are logged in the Secrets tab of your journal.
Herbology
Herbology is the 33-entry set of berries, herbs and mushrooms you gather in the wild. Each region has its own plants, and every type you pick for the first time is logged with a photo in your journal.
