I use a set of small/medium jannd economy paniers

- one side has road morph pump with guage, spare tube, patch kit, tire levers, small bottle of chain lube, rain grear (old cape/leggins), battery for L&M ARC front light, cateye (10 lcd) back light, denoite back light, local city bicycle map, small cable lock, sunglasses & suntan lotion, leg warmers, arm warmers.

- other side has change of clothes, small thermos for morning coffee & lunch

Purchased L&M Arc front light on eBay for $300, denoite back light was xmas present, bike has fenders & rack. Always carry rain gear since it is always raining here in Seattle. At work is good ulock - although area is fairly safe. Paniers come off at work and are stored at desk.

I would also be on the phone trying to get any unusable bike lanes cleaned of debris. If there is a bad patch on the road & local street crews are slow to clean up - I will on occassion - throw a small broom & dustpan into my grocery panier and clean it up myself.

Good luck with your commute.
