If you are looking to buy a ticket for a sold-out program, or if you are looking to sell a ticket to a program you can no longer attend you'll find a tack board in the registration area of the Palm Springs Convention Center where those with event tickets, such as Award Lunch tickets, Field Course tickets, Short Course tickets, etc. can post a notice they have a ticket for sale. Additionally, there are forms available on the board for those seeking to purchase tickets to an event or program — you can also tweet availability #CAscience16.
