This is the first episode of the podcast “200 Degrees”, recorded entirely inside a homemade backyard sauna that the host keeps at ~200 °F (it briefly hit 210 °F during the recording).
The host uses the sessions to talk about whatever is on his mind. In this ~33-minute episode he introduces himself and the show, describes how he built the sauna, then delivers a detailed, practical guide to buying (and to a lesser extent selling) on Craigslist / Facebook Marketplace.
