Tickets are FREE if you register in advance

You must register to attend our expo but the good news is that registration is FREE if you pre-register.  We use Brown Paper Tickets for ticket processing.  You can print your tickets at home, have them delivered to your mobile phone or place them on "will-call" at no cost.  While supplies last, attendees will be given a FREE pair of eclipse glasses and other goodies yet to be named. 

NOTE:  We are making our tickets FREE if you register in advance because we want everyone to attend. But if you can spare a few dollars, we would appreciate a donation to help us fund our expo and purchase eclipse glasses for schools!  See the "Donate to our cause" section on this page.  We accept Paypal and credit cards.

Early registration is important!

Early registration will help us make sure we have enough eclipse glasses and handouts available.  If you want to let us know your school district, please type your school's name it into the "organization name" box when your register (optional).
