We've been holding the Dog Days Ale pretty much annually since 1994 (although there was a break in 1996 and 1997 as the team reorganized). The first three ales were held north of Syracuse, centered roughly on Cleveland, NY. Since 1999, we've based them at Peter Hoover's farm in Trumansburg, near Ithaca, NY.
Our collective memory can't recall all the details of our earliest Ales, but since we've had a website, we've been able to document more for posterity.
