Many listeners probably noticed that there was not a new episode last week, and that was for a couple of reasons. The primary reason is that Ryne has had an extensive international travel schedule in the second half of 2025. The other reason is that this time of year is extremely busy at Hogan as we look to wrap up the year. But that got me thinking. How well do you, our listeners, know Ryne and Blake? In this special episode you get an in-depth look at Blake's life, and a similar episode featuring Ryne will be published in the coming weeks. Cheers!
