tcs' hot tip: use good locking protocol.
Machiavelli's hot tip: lock up next to a nicer bike secured less well.
Several years ago a woman and I locked our bikes next to each other’s at the same time. I used a Kryptonite u lock and thick cable to secure my LHT. She used a cheap chain and padlock to secure her Trek road bike. She went into the market. I went to get a paper. As I was returning to the market I saw a tweeker looking guy speeding the wrong way down the street on her bike, small duffel bag over his shoulder. Hadn’t even been 10 min. More like 5. My bike was untouched.
