After having my bike stolen while locked on the side of a Walmart, I am more protective of the new one. I'm a bit more aware of where I lock it, but I also bought a decent U-lock instead of just a cable.
But I also stopped using my own bike if it isn't an absolute necessity. Sometimes I need the bike for the panniers or the trailer, so I take a risk. But if possible, I'll use a bike sharing system when I go to some sketchy places.
I even got a bike stolen in the garage of my apartment complex, so now it lives with me, in my studio.
Not really.
