'''[[Bowling]]''' is an indoor sport in which a player rolls a large, heavy ball down a polished wooden lane to hit a cluster of pins in order to achieve the maximum amount of pin-falls. Although an individual person can play a game, most bowlers compete against other players as each of them tries to attain the highest number of pin-falls for that particular game.

Most bowling alleys today have not changed much since their initial construction many years ago, except for mechanical and computer system upgrades. Unless the alley has undergone serious renovation it is not unusual to see the original tables, chairs, fixtures, walls, and ceiling tiles. There are, however, a few very modern, "upscale" bowling alley establishments such as [http://www.bowlluckystrike.com/ Lucky Strike Lanes] where "proper" [[Bowling#Attire|attire]] and behaviors are expected. <font size=1>[[Bowling|['''more...''']]]</font>
