Michael, AGU meeting is about $300 for members (may or may not include SSA), or half that for one day. Notice I'm not there...could not go because someone has to stay home with our daughter, but also because of cost (for me, add plane and hotel, and food). We generally put in $ for meetings on proposals, but I've already been to Turkey and SCEC (Palm Springs), which is enough for me for 1/2 year.
