I have my tricycle at work locked up outside, with a Citadel type lock, but better. It actually runs 2 bars through the case hardened ends of the U piece. One of the guards at work showed me the footage of one guy going up to it, taking at look at the lock, and a look at his bag, and just walking away. Tech Team is the brand, but this one is an old one. Situational awareness is key, around home. Know who lives in the neighborhood, keep an eye out for each other as neighbors, and keep a low profile and low visibility of what you have.
