Where are John Rendall and Ace Bourke today?

As of my last update, John Rendall and Ace Bourke are known for their work with Christian the lion, whom they raised in the 1960s. They have continued to promote wildlife conservation and animal welfare through various projects and public speaking engagements. Both men remain active in sharing their experiences and advocating for the protection of wildlife. However, for the most recent updates on their current activities, it would be best to check the latest news sources or their official social media accounts.
