More than 200,000 Danish citizens have signed a petition to buy California as a response to Trump’s attempt to take Greenland.

They say they will provide Californians with “rule of law, universal health care, fact-based politics, and a lifetime supply of Danish pastries.”

A year and a half ago, 2024-06-06, we went over Catalog Number 59999. Yesterday, we passed 66999, meaning we have less than 3,000 catalog numbers left. At the rate for the last 1,000 (55 days), we have 165 days left or until 2026-05-24. Time is quickly running out to prepare.
