Second Look w/ Claudine Wong: From Backyard Roller Coaster Dad to Building a Giant Sphere – Catching Up with Will Pemble

In this episode of Second Look, Claudine Wong reconnects with Will Pemble — better known years ago as “Roller Coaster Dad” after building elaborate backyard coasters. Since our first conversation in 2018, Will has been busy moving back to Connecticut, creating custom Sprinter vans, experimenting with geodesic domes, and—most recently—constructing an 18-foot wooden sphere that’s become both a neighborhood landmark and a surprise concert venue. With Will, there’s truly never a dull moment—we talk about his endless curiosity, his family’s patience, and the joy of building just for the sake of fun.  [00:00] Welcome back: reintroducing Will Pemble [01:00] Flashback: the backyard roller coaster story [02:30] Building the “Gold Boss” coaster with his son [05:00] From Roller Coaster Dad to new adventures [06:30] Life changes: moving East during COVID [07:30] Custom Sprinter vans (including a $300K one!)
