I've played the trombone since seventh grade. It has always been for fun, and has included playing in concert bands, orchestras, big bands, marching bands (including the Husky Band) and even a trombone choir. 
My kids didn't take to music, but my niece and nephew did. As a matter of fact, they play much better than I ever did. I recently received a photo of my nephew playing trombone in the Sound Wave, the Sounders FC band. I had to share it. My nephew is the big guy in the middle pointing at the camera.
