whitewater rafting

A fun activity where you put on PFDs (layman; "life jacket"), jump in a rubber raft with little PVC paddles and float down the river....no big deal...until you get flipped over, hit on the head with a rock, hit in the teeth with a paddle, flipped out of the raft, pushed out of the raft, or are simply scared out of your mind and go into fight-or-flight mode with those class 5 rapids coming around the bend.

I was having a fun time whitewater rafting until we hit this class 4 sideways, our raft flipped over, I got sucked into the rapid and popped out about 40 feet away (still holding on to my paddle)...After whitewater rafting (which was a real rush) driving on the beltway doesn't seem so bad.

MHz

Pronunciated: "Megahertz" not "M.H.Z."

Megahertz means 1000 kilohertz (kHz) and kilohertz means 1000 Hz (cycles per second)

1 MHz = 1000 kHz = 1,000,000 Hz

Wow, sense I listen to DC101, who has a transmitter on 101.1 MHz, thats 101,100 kHz, which is 101,100,000 Hz (cycles per second)

GPS

Global Positioning System

Complex network of satellites that transmit signals to ground receviers in cars, boats, airplanes (see also VOR). The GPS receiver uses the signals from the satellites (which are over 15,000 miles away!) and uses them to find your location, anywhere in the world, with incredable accuracy.

Without GPS, countless losers who can't use a VOR would be lost"
