start clean & when you get to the office there's less to do. when I bike commuted (17 miles ea. way) w/o a work shower, I showered at home. when I got to the office I sink washed with a soapy washcloth, did the hair w diluted shampoo in a big plastic cup & rinsed the same way. it required getting up pretty early & carrying more stuff, including a towel. thanks for the reminder cuz I've been thinking about trying it where I am now (22 miles ea. way)
