Spring cleaning season is here! Join Common Horizon Calgary on March 29th from 1 to 4 pm for a book swap at Renfrew Community Hall! Feel free to bring books to swap or donate or just show up to find your next read. Political books encouraged! As we begin cleaning out our homes and bookshelves, we have to wonder: Why won’t oil and gas companies clean up their mess? (And why do our leaders continue to let them off the hook?). At the book swap, we will have information about Clean Up Your MAS — our campaign to protect taxpayer money and ensure that oil and gas companies are held accountable for cleanup. Join us to clean out your bookshelf, protect public money, and join the fight for oil and gas cleanup.
