STYLETHREAD -- LET'S TALK SHOP!

Any tips? I'm thinking about biking to and from work, now that the weather is cooling down a bit. I only live about 3 miles away, so it won't be a terribly hard trek (although going home there will be some killer hills). I'll be going through a few blocks of downtown but there are bike lanes the whole way, so that shouldn't be a problem.

Any essential items I should have? (i.e. hair revitalizer spray, carry-alls, etc.)

My only friend who bikes to work has a shower at work so she does her whole routine there. I don't have a shower (and I'm not anticipating being too gross since it's in the 60s and 70s when I leave for work) so I'm open to any suggestions.

TIA!
