Letter From Ellen Sharp: First Virtual Tour at Cerro Pelon Monarch Sanctuary

South of Sierra Chincua and El Rosario at Cerro Pelon Sanctuary, Ellen Sharp details the first virtual monarch tour of the season and provides a message of hope during unique and difficult circumstances. She writes, "Our sanctuary is closed to visitors this season, and so we decide to film our first virtual tour, given by my sister-in-law Ana, who’s an experienced butterfly guide . . . In this season without visitors, we have been given the gift of time, the time to create things that can potentially reach more people."
