Since this is the last day (I hope) for this cast I let my seminary students sign it at the end of class. They want me to keep it - we'll see. I suspect it will be rather 'ripe' - after all, it's been over 7 weeks since this arm has been washed. I shudder whenever I think about that. The cast is pretty cool - I highly recommend the "glow-in-the-dark" option if you want to impress kids. Since they signed the cast I can now read their names in the dark. I may have to keep it for a little while just so I can show it to them. Then I'll toss it.
