Rigger Greene exploring
So like a lot of people I'm stuck at the end with not enough pins. I've completed all the side quests and bought out the stores. I gave Rigger Greene all his photos and told him to go to Autotopia but I can't seem to find him nor have I collected the pins related to his quest. Am I missing something? I can concede the Pin Collector achievement if I can at least get these last few for Statue Garden (awakening the spirits).
Any help is appreciated since no one has a complete list of these pins anywhere online. I'm stuck at 164/176.
