We have a secure area (badge to get in) outdoor area to store the bikes, dark so clothes wouldn't dry. I think decent fast drying clothes, rinsed if possible and dried under my desk with a fan is my initial plan. Thanks to everyone for their suggestions, I'm looking forward to riding and will report back-most likely April after my first ride! Initially I'll only ride one way-to work one day, home the next, will mean the clothes won't be an issue, but the plan is to ride both ways 2-3 days a week.
