if you lock up regular at the same place, say college, buy a cheap and heavy duty motorbike lock, or even a big chain and padlock from a hardware place and leave it there 24/7
Just a wee word of warning, if its an exposed area beware of the superglue sting !
rely on the fact that bikes are left unlocked for however briefly whilst you go and get the stuff. Another horrible outcome is you cycle x miles to work find your locked jammed but don't have time to go home and get the stuff or another lock
