Arielle, if you go directly to the Calender, it removes events once they have happened so you won't have that happen again:
http://garden.org/apps/events/ But yes, plan for next year! Some of the annual events I've been talking up I keep telling people to plan for next year if they can't make it this year. We have a lot of really big events that are often multi-day events. Sounds like a perfect reason for a Florida vacation!
