Just had a thought (ouch!):
A number of people wanted to hike specific peaks because of personal value. Perhaps we could have an early registration whereby those with personal attachments to certain peaks can apply for one before the general first come first served group starts.
These folks will have to write a short description on why they wish to have that certain peak. The result will be 1) These people will most likely commit to their peak as they expressed a personal attachment to it and 2) we’ll have generated some early publicity sources to use throughout the event.
