Sin's Trap - Overpass

Starting Day 4, the first tribute to post in the Overpass will stumble across a gift left by Sin.

I'd like to leave a small bundle underneath like... a rock or something in the overpass area for another tribute to find compiled of these items:

canned spam, rusty knife, matchbox, antivenom

They're bundled in Kane's bag with a notepaper from Sin's notebook. The notepaper just has a smiley face written on it in blood.
