How To Lock Your Bike

Yeah,
I work on the Olympic Park and this is all that's available.
Kinda compensated for by the fact there is a security type standing next to the bike racks 24/7, but still less then ideal.

I go for D-lock through the bike rack, rear wheel and seat stay then a shackle front wheel to frame.

So you put the rear wheel of the bike into the rack? Wasnt sure the bike would stay up like that without some support?
