I have posted the text of the document Brent N linked to above as well as a "Talking Points and Frequently Asked Questions" doc in this thread:
    Mt Whitney Permit Reservations 2012

I think the biggest issue for people is that there will only be ten possible entry dates that they can choose in the lottery application. And each of those is a specific date, not a range of days. I am hoping people here, along with folks at Inyo, can raise enough support to get the NRRS reservation people and their subcontractor to change the system to allow entering the range for the next round. From a computer software development standpoint, it would not be a huge task to enable checking a range of days.
