Sketches from a Conference

I recently attended a conference for leaders of Christian schools. Really good stuff - it definitely recharged my batteries. I was able to meet Jon Bauer (www.jon-bauer.com) at the conference. He is an award winning Christian musician from Canada. Good stuff.
This sketch and the one below were done during the conference. As I have noted recently, I find it just a bit easier to concentrate if I have something to sketch.

If you have ever stayed at a Doubletree hotel you will recognize this logo. Both of these sketches were done on notepaper supplied by the hotel. On the sketch below I found myself tracing and then filling in the logo. Truly a mindless doodle, but a concentration aid. Do you do this too?
