In the meantime:
The March for Science takes place on April 22 in Public Square at 9am. There will be kid friendly activities like face painting, fun with water, etc until 10am along with speakers. THEN WE MARCH! I will be going but am volunteering with the organizers and will not actually be marching. If anyone else is interested in volunteering get ahold of me and I'll see what we can do.
They are also asking, if you can, that you go out to the fair grounds for the Earthfest. I think you can take the red line straight out and if you show your RTA pass or ride your bike you can get in free. Earthfest
There will be a sign making party on April 20 at 7pm at the Happy Dog Euclid Tavern. Some materials will be provided but bring anything you want to use or would be willing to donate.
Signage party!
In case you are looking for signspiration here are a couple of sites that you can use for ideas or download and print. The first and third are free and I believe the second is for money.
