Terry,
We are planning to leave around 3am, but getting 8 people to be on time could be tough. We are camping at the portal so that should help but we may get a little later start. I just want to be back in time for the (hopefully) celebratory burgers. If you are starting around 1am I am sure we will see you on the trail somewhere.
I am sure that you and your sons will do well. We range in ages of 16 to 52 and five of us have been to the summit. If you want to leave a little later and join us send me a PM and we will get a plan together.
