schedule tweak

my accomplice decided to bag the architectual highlights of PA for now.  as a result we've just cancelled the PIT run and are extending our time in new england (and resulting in a closed jaw flight).

again, no problems (and no charge!) with the booking changes ... the only catch is things are getting full enough that we have two middle seats on the flight at the moment -- one in front of the other -- if we keep an eye open we may be able to snag better seats once everyone else starts changing as well.
