BTW, someone mentioned earlier about making sure scrotes don't know you have nice kit, make sure that you lock your social media down, Facebook, Google plus etc. Pictures and statuses for friends only, not friends of friends and so on.
There was a spate of high end bike thefts in the US last year, basically through using social media to locate the high end stuff (strava, fb, g+) and to work out when would be best to burgle the places. And if you think a Baja costs a lot to replace, you should have a flick through some bike retailers websites!
30 seconds on my Facebook found two known bike thieves (friends of non-cycling friends) and another friend of a friend who has a serious grudge against me (I don't particularly like associating with people who beat their wives, so he took offense!)
For the sake of 10 minutes, could save a lot of grief.
I mean, you know all the people on your friends list (well, I do!) do you know all the people on your friends, friend lists?
