Just a general question to get a feel of how often they get stolen.. For people with ventura rack and bag, I was wondering how many of you actually take the bag with you to your workplace or do you just leave them on the bike... They are not cheap at all.. over $100 for a new one if they get stolen.. If you don't take it with you, obviously you lock them up to the rack with some sort of hard wire cable or lock. Where do you get it from? I've checked BigW or Kmart, those bicycle type hard wire looks a big chunky. Also, if leave them on the bike even with the cable and lock, do they get stolen often?
