I voted BL #1 against my biggest dislike. I absolutely hated the population density of his location. However, I trusted the research he did on sustaining a power source within the facility. If his location remained energized, I really liked its sustainability.
As for my location... I never looked at Site-R as a negative because I'd always considered in "part" of my location. And that was a misplay on my part. Your analysis of it being a potential "open-door" is completely valid.
I'm just so stoked I found that Marcin guy. I did so many worthless hours of research to find an unknown apocalypse stud and he simply awes me in every way.
If you take anything away from the team/plan I put together, take a look at the crazy stuff he's doing. The thought of building every essential industrial tool from scratch, using only recycled material and not requiring a fuel source is simply astounding.
