Thank you Dien for the response and the Dell and Magic story. I will definitely look for Dell's book and share it with my son. I have every intention on helping my son learn and in the process learn something myself. I believe we can learn a lot from our children, we just have to give them the time to teach us.
My son and I take the ring to malls and parks. Talk about a crowd builder that turns into a sale builder, again another idea of my son's
I found another site that explains the ring a little better if you are interested. I tried to find videos, but the ones I found were bad quality.
Take care all,
Dennis
