Pins are cool, they give our crag "character." Leave 'em, replace 'em. Clipping them here gives me a feeling of home. Comforting to clip, safe to climb past, but still not commitment free like a bolt.
What happens 100 years from now when all the bolts are loose? Do we throw the cliff away like we throw everything else away? Bolts freak me out. I have had them snap on me before, although I talking old ... but that is the very point I am trying to make! You can toprope anything. You can even top-roped things like Suppers Ready or Twilight Zone. No need for bolts unless you are on a big wall. All the pins could be pulled too. Which ones are essential? I know of none.
The Mohonk Mountain House and the Mohonk Preserve have done a great job protecting the environment thus far, but ... it's all down hill from here http://youtu.be/9AU8fMo8v4k.
