Mt Whitney Zone Forums General Discussion Permit question...what are the ramifications?

Good topic. Question--what about the entry point? E.G., I have a Inyo permit for entering Taboose Pass (I think) and exiting the portal. What if I enter somewhere else, like up Baxter Pass or Onion Valley? What if I don't exit the Portal the day it says (i.e., earlier or later)? Or what if I enter Taboose Pass and go north, and exit somewhere else?
