Great idea,when I was small I was not allowed to lose one lol.Looking back 45 years or more,don't think I ever lost one.The "What may happen" if you lose it was something I knew first hand.My how times have changed,my two boys ,could never be that harsh.I think a lot of us know what I'm talking about?.
Having said that,looks like Nick you now have a couple other options. Love your reports with the little guy.!!!!!!!!!!!!!!!!!!!
