Moved back to the east coast and am sorely missing my 24 hour fitness membership - especially the cost and the classes.  I've been a member of various gyms over the last decade, and 24 hour fitness seems to go the farthest in making sure its members are happy, are not restrained by high costs or contracts, and have choices in equipment and classes.  If they open one in DC, I'm sure they'll snatch away business from the other fitness centers here in no time!  Reason for 4:  pay for towels, not completely nationwide yet, and the machines aren't as nice as some of the fancier gyms.
