Here’s my ideas for special resources or creatures that could spawn randomly in the Tahoe area. They would be announced like:
The Old Forager/Scrapper shouts: I was [scavenging/foraging] up in [area] when I came across [node]. I’d never found such fine stuff, but before I could gather anything, I was chased off by [bears, coyotes, zombies, rabid pine martins]. I’m too afraid to go back, but you are welcome to try.
The Old Trapper/Pioneer shouts: I was up in [area] when I saw old [critter name]. I’ve never before seen such a large and fearsome [critter type]. I’m not the hunter I used to be, but if you are looking for a good fight you are welcome to try.
The resources from these nodes, creatures would have a +5 to normal quality so that a high level scavenger/forager/hunter/logger/fisher would have a chance to get supreme quality goods. Nodes would last one game day, but could be depleted faster if gathered rather than scavenged. Special critters would wander around till killed. Critters would also have higher than the normal quantity of bones/leather/fur (but not head/legs/paws) including the full complement of bones from giant sized small critters (rat fur, round marmot bones).
Special Resource Nodes:
Military plane wreckage -- titanium sheets, plates, fasteners, handles, etc.
‘57 Cadillac -- chrome sheets, plates, fasteners, handles, etc.
