I received a mysterious postcard this week:
No obvious hidden messages jumped out at me from the text, but DeeAnn wisely pointed out that several different video games are mentioned or described. That's pretty interesting.
Without knowing where this might lead, I'm not very motivated to spend time trying to solve it... but I'm sharing it here in case somebody else out there wants to take a crack at it.
If you do figure something out, please leave a comment below! (I also don't care about spoilers.)
