If my quick math is correct, New Horizons is going around 30,000 mph. For some reason I thought is was going two or three times faster.

I know it's been losing speed but I could swear I've seen a speed quoted much higher than your estimate?

According to the New Horizons mission web site. The heliocentric velocity is 14.28 km per second (31943.45 mph).

The early high Heliocentric velocity was mostly from Earth's orbital motion being included.
