go to the www.scijellyfish.org and see whom has volunteered. Go to the service page.  If the slot is filled, consider writing to the coordinator for that area and see if there are any additional slots.  You can access the regional by clicking the contact name provided next to the venue name and date.  It hyperlinks to the regional coordinator's email box.

 

BTW  there will be a table at all the SCI Big Summer Tour this summer.  Please consider volunteering and come out and see live music.
