Gene,
My 17 year old son and I (57) are planning to start at 11 pm on Sunday and you're welcome to join us. We are in good shape and have trained, but we're also prepared to abort at any time if we don't like the weather or don't feel good. This will be his first time and my third, but only second from Portal in one day and first in winter. We have our own passes and will be camping tonight and tomorrow night at Whitney Portal.
George
