Don't forget to lock your door(s) at home. In nearly 30 years of locking bikes outside, the only thing i have had stolen is a seatpost QR. A week before this past Christmas we inadevertantly left our front door unlokced when we got home from dinner. Later that night, while we were upstairs in bed watching the news, some crackhead who was aparently trying doors discovered our oversight and I lost my Surly LHT with a custom Bekcman rack attached to it. Thank God he left the two IF's including mine, which was actually the closest bike to the front door. I know far more people who have had bikes lifted from yards and garages than from the street.
Now we lock our two Surlys to each other and do the same with the IFs.
