I struggled with this one, caconym_.

A few minutes before I had this idea, I wrote down "Faraday Cafe. No wifi. No cell signal." But then I thought about how hard it might be to build one that blocked modern 5G/wifi networks. (Can any RF/electrical engineers weigh in?)

I scribbled these ideas with pen and paper while getting breakfast this morning (phone and laptop put away). Then I went to a park to write the post on my laptop (without a network connection). Then I turned on my phone and hotspot in order to post it. (An hour later, I'm still gazing at the internet.)

I'm super open to other ideas.
