We sent up extra gear with the 'bot (they weren't allowed to bring in food, electronics and such), and he gave away a compass, some rain gear, soap and toothpaste to the cadets who forgot to bring those things. I was shopping with him for two days for all of this stuff.
I think everything comes out in the wash at the end.
He laughed at me for sending up with him individual hand wipies. They were all gone when he got back.
Next year Cyber and I are going to work this little soiree. It should be fun, to say the least. We'll be staying in a HOTEL nearby, though.
