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? 😵

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.

Robber Baron Cave
Saturday February 10, 2018 From 9:30am to 5:00pm
Hosts – Rob Bisset & MJ Gibbons & Daniel Pedrotti
A total of 32 Scouts and Scouter Adults visited the cave from 2 BSA Troops and 3 BSA Crews.

Sunday February 11, 2018 From 9:30am to 2:00pm
Hosts – Rob Bisset & MJ Gibbons
A total of 21 Scouts and Scouter Adults visited the cave from Cub Scout Pack 307.

Air quality was great (for robber baron standards).

59 Tri-Colored Bats (Perimyotis Subflavus) were scattered throughout the entrance hall enjoying their peaceful slumber. With adequate precautions, all persons exhibited exceptional considerations to not disturb the bats. zzzzZZZZZzzzz

Despite our best efforts to push these kids beyond their physical limits, all easily climbed, squeezed, crawled, contorted and asked for more.

Both days we had great surface security and entrance control. Paperwork (waivers) were ready, first aid & safety in place allowing maximum in cave time.

Service projects included digging out the mud plug at the natural entrance and hauling excess rock-fall debris to surface.
