My wedding anniversary is May 15th, so I'll be able to remember this!
You know, if my office would allow a relaxed dress code for those who ride their bikes, I'd ride instead of drive. I don't live far from the office, and the local biking/walking trail runs right by my office (and is close enough to my home to access fairly easily). But if I'm expected to be dressed in nice clothes every day, no-can-do on the bike ride. We don't have a shower at the office, and dressy clothes won't travel well in a backpack when I'll have to pack my lunch in there, too.
