I'll be there on my green track bike with yellow lugs rocking a tuxedo tee.
Money is due at the start of the ride or they won't give you a number.
Good luck with housing. Sometimes you can find something once you get to Ocean City. There's a tent somewhere at the finish line that helps people out if they need housing. It's really a last chance though. There used to be an Ocean City hotel guide linked off the MS site, you could probably try getting in touch with them.
