Traveling Leagues have been around for a long, long time in areas where there are multiple bowling centers within a relatively small area. The league sets up a rotation among different centers based on availability at the beginning of the year, and then "travels" from one center to another. This way bowlers get to experience different lane conditions. The other four lanes (two pairs) were not being used because centers do not normally put open play next to league bowling, and they have to reserve one or two pairs in case of breakdown of league pairs.
