Mobility is an essential component to the vibrant, equitable, and sustainable cities of our future. To build this future, we need to do more than invest in technology. We need to invest in the people who will make the hard decisions around transportation, land use, housing, economic development, and other aspects of urban life. Josh Cohen, National Policy Director at TransLoc, wants to start that conversation by building relationships with and sharing ideas from today’s leaders who are imagi ...

Welcome to ‘Safari Conversations’ – the Singita Podcast. 30 years ago, our Founder, Luke Bailes, had a dream of creating a pioneering ecotourism brand that could help save pristine wilderness areas in Africa for future generations. The first chapter of this story started when we built Singita Ebony Lodge, in the Sabi Sand, in 1993. But truly, it began long before that, on a piece of land his grandfather owned and where they spent holidays as a family at Castleton. So much has happened in the ...
