Keith's note: At a time when NASA science budgets are being slashed, I find it to be a little odd that USRA, a non-profit that could simply not exist without a constant influx of NASA funds (and the overhead that they charge on those funds) is able to find the money to host a reception for 5,000 astronomers - and to be telling everyone that they have done so. Receptions like this can easily cost $20 to $30 per person - or more. Perhaps USRA can tell us what they spent on this. My guess is that it would cover a good portion of someone's college education.
I guess this was what it was like when Rome was burning.
