I would like to know the hours of operation for the DART and the light rail service in Dallas, Texas. Need transportation to get to an evening Hockey game at American Airlines Center. Would like to know what time the train service stops?

The dartboard itself may have its origins in the cross section of a tree, although some historical records suggest that the first standard dartboards were the bottoms of wine casks, hence the game’s original name of “butts”.
There is speculation that the game originated among soldiers throwing short arrows at the bottom of the cask or at the bottom of trunks of trees. As the wood dried, cracks would develop, creating “sections”. Soon, regional standards emerged and many woodworkers supplemented bar tabs by fabricating dart boards for the local pubs.
The numbering plan known by many today has a 20 on top; however, a great many other configurations have been used throughout the years and in different geographical locations. By most accounts, the numbering layout was devised by Brian Gamlin in 1896 to penalize inaccuracy. Although this applies to most of the board, the left-hand side (near the 14 section) is preferred by beginners, for its concentration of larger numbers. Mathematically, removing the rotational symmetry by placing the “20″ at the top, there are 19!, or 121,645,100,408,832,000 possible dartboards. There are many different layouts that would penalize a player more than the current setup; however, the current setup actually does the job rather efficiently

The throw line (also known as the oche, toe-line or hockey) should be about 3 feet wide. It may be made of tape, a store bought throw-line sticker, a piece of wood or metal. It should be placed exactly 7 foot 9 and 1/4 inches from the FACE of the board for a standard steel-tipped setup.
For soft-tipped darts, the line should be 8 feet from the FACE of the board. (NOTE: Some British pubs use an 8 foot or 8 foot 6 inch measurement for steel tip darts.)
To measure from the face of the board, have someone hold a plumb line from the bottom-front of the board to the floor. If you don’t have a plumb line, you can use a piece of string with a pencil or dart tied to one end. Make sure the throw line is exactly perpendicular to the face of the board and centered with the board.

Ever asked yourself how you are to supposed to figure out your average in a game of Darts?

To work out averages, simply divide the points scored by the number of darts thrown, eg:

If a player wins best of 3 501, 2-1, and the legs he wins he finishes in 19 & 23 darts, and the leg he didnt win he was left with 106 after throwing 18 darts, you would work it out as follows:

3×501=1503-106(score left)=1397/60(number of darts thrown)= 23.28 per dart average

It’s classified as a sport (a competition between two people or two groups of people). In this sense, Chess is also a sport.
Sumo wrestling is a sport except sumo wrestlers are at least twice the size of a darts player. Besides which there are thin and medium sized darts players. Fishing is classed as a sport but I cannot see the point of sitting on a river bank for hours on end with the company of a plastic tub full of maggots.

Darts is not a very good sport for keeping yourself physically fit and some of the professional players are overweight, but this however does not stop the game from being classified a sport.

Darts have been happening for hundred`s of years, In 1530 Anne Boleyn gave Henry V1111 a set of dart`s, and in 1620 the Pilgrim Father`s even played dart`s on the Mayflower. Brian Gamlin invented the number system on the dart board in 1896, but never had it patented before he died in 1903, so the honour goes to Thomas Buckle who says he invented the dart board in 1913. So I leave it up to you who you believe.
