I personally believe in our area, NC South Dakota/SC North Dakota, drought has had a much of an impact on bull sales as anything. Last year was the worst drought on record. This trend continued into the winter, and seems to be continuing

.
Cattle prices have been pretty high, so if you're tired of fighting for feed and water, selling the most of the herd probably looks pretty attractive, especially if you're older and can rent your land for the high rent prices that are being seen nationwide. I also think high corn prices have not helped bull sales any either. And, then add in that 2006 was a year of record bulls sale with lots and lots of bulls selling for high prices. There is a point in time when folks just have enough bulls. I know at our place we bought three really nice herd sires last year, and thus aren't in desperate need of replacement bulls, even for our commercial herd. Demand wise I think this pretty much hits it in our area.
I don't buy the border rhetoric here, OT.
The supply side is just as outta whack as the demand side too. There is an abundance of bulls, plain and simple. We've been told the guy who carcass ultrasounds for us had ultrasounded 500 more bulls this year, over the same timeframe and same number of operations, than he did last year.
At our place, our fire laden month of July and early weaning the end of July/early August helped us make the decision to cut more bulls. Lots of good young bulls got cut because of a lack of feed and rising corn costs. I know we did not catalog more bulls than last year, and maybe even less. However, if we had not had our fires/drought, our decision might have been different.
I say it's good ol' supply and demand hard a work, along with the added measure of drought.
