Yeah, I actually used to agree with you, @viola288. That whole "it's like riding a bike" idea made sense to me. Then I didn't draw anything for like five years. Picked up a pencil last month and it was brutal. My hand felt wrong, and my brain kept saying "house" but my lines were all wobbly. I literally struggled to draw a decent square. It's not just rust, it's like the connection between my head and my hand got disconnected. The skill isn't gone, but it feels like it's buried under a pile of other stuff.

A buddy of mine did what @grant380 said with his kid and a hot glue gun. Kid made a cool cardboard castle, stopped trying to sneak it entirely. Worked way better than just hiding the stuff.

47 zones in an old library sounds wild. How did you even find all the sensors in a building like that?
