This morning I got to work and when looking for my keys recalled I'd put then in my rucksac and then left it at home in favour of the bike box.... Not a problem me thinks, lots of folk at work who leave their D locks so I borrowed one. But then when I went for a shower I remembered my locker keys were at home on my key ring...
I had to give in and call my GF to drive in (early) to bring in my keys whilst I festered at my desk in sweaty Lycra :-(
I think I need a spare key for my aging D lock (currently only have one) and leave it with my locker keys in my desk draw.
