We hope you can make it May 20 (schools) and 21 (public)!
It will be a huge help if you practice using iNaturalist before the BioBlitz!
Check it out at http://www.inaturalist.org/pages/getting+started
We will be posting a schedule of events soon.
You can also get lots of help with identifications by joining the Vermont Atlas of Life project:
