THAT is the point of their actions. They have removed, closed, or restricted nearly every campground at Lake Tahoe, a place where I grew up camping. They've already removed several popular campgrounds at Yosemite, another place I'd like to take kids camping. THEY DON'T WANT US TO USE THE PARKS. The more uncomfortable they make it, the less we use it. Mission accomplished. And, no, I don't need a tinfoil hat for THIS one.
I haven't been to Yosemite in years, but my understanding is that it has gotten very crowded with people and cars. I am not saying buses will help. I am just saying that it's my understanding that the problem cited above already exists. Have you been there recently? I was only there once and it was a dozen years ago. I went to Arches Nat'l Park in Moab, Utah and Rocky Mountain NP in Colorado this year and they were both excellent parks. I had a great time.
