[pct-l] Mount Whitney Zone entry date

[Simon Deleersnyder]

Hi all,

I have a question about the PCT long-distance permit. It asks me to give an
entry date for the Mount Whitney Zone but it's really impossible to plan
when I will enter this part of the trail, as this depends on so many
things.

Is it crucial that this date is correct? And if it is, can I change it
later or do I have to get a new permit and pay another 15 dollars?

Regards,
Simon
