Nightly Spirits Tour in Denver took us underground to haunted tunnels and historic structures, including Blake Street Vault, Double Daughters Salotto, Oxford Hotel and Cruise Bar and Union Station.
Built by the Spanish in the 17th Century, Castillo de San Marcos is a prominent feature of St. Augustine's coastline in Florida. It's the oldest surviving fortress in North America located in the oldest European-founded city. It's walls are made of coquina, a native stone. It's changed national hands a number of times and is reputed to be haunted as well. In addition, I've posted a Brazilain Daiquiri recipe included for summertime!
