The second annual Gall Week is coming up, and it's going to be a little earlier in the season this time around: Saturday, September 3rd to Sunday, September 11th. To participate, just join this project, find as many different galls as you can during that time window, and add each observation to the project.
If you have any questions or comments about Gall Week, please post them here.
Thanks to @merav for getting this going!
