When I first joined the Rhythm X, Inc. team these guys at the Roundtable invited me to do a podcast on earplugs at X as a follow-up to a hearing protection podcast they had previously done. I'm a huge fan of Etymotic Research. I even endorse them in an official capacity as a "Signature ETYHead" so that led us on to this hearing protection topic.
The Marching Roundtable does a lot of good in our activity. They recently started a program called The Judges Academy, an educational series for aspiring pageantry judges, educators, and fans. I was happy to be a beta tester for them. It's a pleasure to work with these guys in any capacity!
