Great idea, Denise!

If someone can find my lost cutting board, I will donate it. It was last seen under the Oztotl tent at ICS in Kerrville. High-quality professional type cutting board worth about $ 80.

I have a hundred wood sporks.

Trevor and I will be willing to donate most of this stuff when we return. We had to buy a lot of this stuff for our apartment here so we will have duplicates once we get home and unpack this spring.I'll message you when we return and see what is still needed. Or you should post this announcement again around March time in case I forget.

I have two large (3qt.) plastic pitchers with lids that I can donate.

I have a box of stainless steel pots and pans to donate. There is a large frying pan, large and medium pots and a small frying pan.

I have a large box of large stainless steel plates for serving food and also for individual eating that I will eventually donate to a caver group someday.

Not bad, good for a full day of caving with minimal sweating. Not as cold a Punkin.

Joe Mitchell might know.

It's hot I that cave. I'd say 70

Probably a bit higher than 70, but if you want Joe to respond, try e-mailing him.

Someone had data loggers in Deep several years ago...

Great design!

Any volunteers yet, Chris? I could pick them up from your house tomorrow. I'm heading to TCR Thursday.

Me lo perderé otra vez 🙁

If you have any left I would like to buy....

So how did sales go?

We actually had quite a few left over. 30+ all sizes but the small ones. People loved them- I think we just didn't have the amount of people at TCR this year like we had hoped.

Oh, I believe we may have sold out of the mediums as well. Possibly one left.

Great shirt. People really liked it.

You just never know. Sold out last year Saturday afternoon, so I did about 12 more this year, just in case. People will buy them at other events & next year, too. I never had trouble ditching my leftovers (mostly from the rain-outs) at the next year’s event.

We have a few double X last I looked Don.

Double x..xxl? How do these guys even cave?

If there is an M left I'll take it.

Pam save me a medium tank top

Hello everyone! The Robber Baron Open House will be on November 11th, and I wanted to reach out to our volunteer base. If you are interested in volunteering (and haven't already contacted me) please send me an e-mail at evelynn@satx.rr.com and let me know, 1. If you have a preferred job (In cave, gear table, check in, etc.) 2. Your availability for the day (morning, afternoon, all day). The morning shift usually starts by 7:30 and goes until noon. The afternoon shift starts at 11:30 and goes until we are cleaned up. Once I get everyone's interests, I'll assign jobs and positions around the end of this month.

There is also a substantial rumor that an after party will be held at the home of Robert Bisset and Eileen Missy Egan, so keep that in mind too. More details to come.
