I haven’t started commuting just yet. I am moving to D.C. on Friday; I was just trying to get a head start on what to expect. I don’t have a job or anything, but it seems as though finding an office with a shower isn’t completely out of the realm of possibilities.
In Austin, Texas, there’s a place called Mellow Johnny’s (Lance Armstrong’s store, but you’re probably familiar) where you can park your bike in a secure place and take a shower for $1/day, then head right next door to grab a cup of coffee at Juan Pelota’s before heading to work. It’s a great set up.
