I do not see raising a life time pass by seventy bucks, as much of a hardship on most of us older folk.
Perhaps by doing so it will keep the admission prices lower for the young families and allow them to continue to visit these fantastic places, and parks. That is what is most important, these young folks
Quite frankly I kind of cringe a bit when I see the family of 5 ahead of us in the 10 year old minivan, tent camping, and they get hit for full admission, while us old gomers in the nice MH they just wave through no charge.
