A couple of FYIs re the charity auction:
>> USFS itself is a 501(c)(3). So AFAIK, the part of the winning bid that exceeds the retail value of the package potentially is tax-deductible
already -- as the auction currently is structured (meaning without a requirement for the bidder to share the pkg with someone underprivileged).
>> The photo of the auction guests at last year's Champs Camp showed two adults, IIRC. Not that there's anything wrong with that, IMO.
I am not a rich person, and I do not find fault with USFS for raising money for itself with the charity auction.
Some rich people are careful not to throw money away recklessly. That's how they became (and/or remain) rich

. (That's not to say that they do not enjoy life's pleasures. Just not recklessly.)
And for many rich people, their time is what is priceless -- and more valuable than their money. So I am finding it hard to imagine that a rich person who doesn't care about skating would waste her/his time and effort to travel to Colorado Springs and show up at Champs Camp.
If the rich person is accompanying a loved one who really does care about skating [and who was the reason for bidding on the USFS lot], I don't have a problem with the rich person being motivated by the desire to give a loved one a special experience.
Compared to the raffle idea (which I don't hate), I think an advantage (for USFS) of the charity auction is the possibility of future generosity from a winning bidder. If the bidder and her/his guest have an absolutely fabulous Champs Camp visit, perhaps the bidder will be inclined to make future donations (unrelated to the auction) to USFS.
[Another possible advantage of the auction would be a slightly decreased risk of stalkers, IMO.]
Hope Josh does not mind

that we (myself definitely included :yes

often end up talking about other stuff in his thread

.
ETA (Jul 18), back on topic re Josh

:
Just noting that tonight he retweeted this afternoon's Sun Valley tweet promoting that he will be performing in next week's ice show. So he apparently does not expect any problem with skating then.
