"Dots," or "the dot game," is a popular golf betting game. It is so-named because winners of the bets mark their scorecards with small dots, which are tallied at the end of the round.

It can be a lot of fun, and also very elaborate, with bets on a wide array of outcomes - closest to the pin, 1-putts, first in the hole, you name it.

Some people call this game "Junk" or "Trash." Do you know of other names for it?

There's a brand new Golf Channel "reality" series in town, and it's called "Highway 18." Think of it as sort of "The Amazing Race" for golfers, and on a smaller stage. Rather than racing around the world, the contestants on "Highway 18" race around Florida, competing in golf challenges and other challenges.

The series debuts July 22 at 10 p.m. ET on the Golf Channel. Ten episodes total will air, all of them in the 10 p.m. Tuesday time period.
