I don't live in a high-theft area and I am surprised that removable items (lights, pump) don't get stolen when left (but I usually take them).
All public building have bike racks but most of them are very insecure. I therefore lock my bike on a solid tampering proof pole but I have been told to remove my bike a few times. At the university I was warned they would remove my bike (I was curious to see them work through my NYcity Kryptonite lock but I did not let them try

) REcently I have had some note left saying I was parking my vehicle in a no-parking zone. To add to the offense, they described my vehicle as a 10Speed bike. Ignorant! How dare they call my Bianchi 27 speed touring bike a 10 speed!
At any rate, I find that while usually we don't face the parking problem that motorist do, it is a drag to have to always lock the bike, take out the front wheel, remove the bag, the lights etc. It add a minute to taking off and it is a shame. But that is the way it is.
