Howdy y'all,
I'm bringing some Aggies to Deep and Punkin February 23-25. Is anyone available to rig Punkin with us that weekend?

They're Aggies. You don't need ropes. Just tell them to tuck and roll when they hit the guano.

Everyone will be in Mexico 🇲🇽

That is Spring Convention, though

"A brief and shining moment" is a good read. Sad, but good.

Thank you for sharing this. Love to see the history

Someone needs to help these geologists with their cartography. Surveyed with laser range finder and compass? 😵

Would anybody care to rig Punkin the weekend of March 9th to 11th? I am taking a small group to the cabin. All are welcome to join. ... See MoreSee Less

If I didn't already have the whole week after that one off...

I would totally do it, but I'm going to Mexico.

I’m in Mexico 🇲🇽 then

If you're going to Mexico and can't rig Punkin for a bunch of Aggies, please comment about it here...

Sorry Jordj :'(

Why can’t they do it themselves? You only learn from your mistakes.

I’m not much help in the rigging department, but if you have space I would like to join your trip. I can camp.

I thought they needed an NCRC trained person along, and a trip leader that had at least three previous trips and was trained by another trip leader. Surely those two requirements would mean that someone knows how to tie some knots and close a screw link and place a rope pad.

Wouldn’t it be easier to just require reading of On Rope and then have a written and practical exam? I’m pretty sure that’s how we learned. Coddling new Cavers is just making them soft.

I'm available that weekend and would love to help out.
