Episode 4.15 is the second of two bonus episodes. The year 2026 marks 25 years since Adam Prince, Doug Kerr, and Brian LeBlanc started the website. This episode features a discussion with Daniel, Tom (a Gribblenation contributor), Adam, and Doug about the past, present, and future of Gribblenation. Learn the story of how the site came to be, how the name was chosen, the hiccups along the way, and where the site is today. More importantly, learn the philosophy behind Gribblenation: To not only tell the facts and the history of the roads, but to tell the stories behind the roads. Next update: Coming sometime in late September 2026 will be Season 5 of the podcast, starting with the story of Route 15 and I-15 between San Diego and Temecula.

Good background info on the origins of Gribblenation. The detailed descriptions accompanying the posted pictures help explain why certain roads were constructed in the first place.
I appreciate that they limit A.I. use to proofreading and readability.
