FWIW when I parked at Pitt all day long I always took off the front wheel, put it beside the back wheel, and locked up both wheels and the frame with a single U-lock. It was a PITA but I never got anything stolen. If I had it to do over I might buy a second U-lock or a chain but honestly I’m not sure that thought ever occurred to me.
I dunno, seemed too much of a PITA to me to do the front wheel off method. I like locking skewers, bigger pain w/ flats, but payoff in daily lockup with one U.
Glad to hear you got your bike back! I used to lock up on the staple racks just a block away on the same side of the street, there is a driveway across from Benedum. I had been doing this for 7-8 yrs on and off, 3-5 days a week using a U-Lock and cable. Never had any issues, but this summer decided to ignore the University signs and started bringing my bike inside and locking it up on a loading dock. It sucks that this crap is being perpetuated by students, that is some kind of education!
