Yes, I am all for increasing the fees. Additionally, as Grand Canyon does, keep a portion of the fees from the rejected permit applications to prevent flood of permit applications, as it encourages now in YNP process. Retaining a portion of the rejected application fee also discourages multiple attempts by the same person or groups.
GC system also keeps the full fee of rejected permit applications, keeping some portion as a credit for the applicant for a future plan, usually to be used within a year. This usually never happens and GC system keeps the money.
I prefer this to the lottery!
