Thanks, all, for the good wishes!
Yes, there's a lot of radio stuff here at the playground we call NERW Central, and Eli's big sister, Ari, likes to play with some of it on occasion. Thankfully, she's shown no indication thus far that she's interested in a career in radio...and Eli's unlikely to have any opinion on the matter for some time to come. I wouldn't (and couldn't) forbid either of them from getting into the field, in whatever form it still exists 20 years out, but I'd certainly sit down and warn them of all the many pitfalls along the way...
