if you go to my home page here, last years peeper post is literally right next to this one. you don't have to scroll down very far to get more of them - you'll get all the way back to 2017 peeper data before you have to click on the "Previous 20" button. Anyhow, the range has been from March 10 at the earliest, to April 12 at the latest. I should post more here and less in New Zuckland.
