Passage: The NASL first staged an indoor tournament in 1971 at the St. Louis Arena with a $2,800 purse. After a couple of years of experimenting, including a three-city tour by the Red Army team from Moscow in 1974, the league again staged tournaments in 1975 and 1976. For many years Tampa Bay owner George W. Strawbridge, Jr. lobbied his fellow owners to start up a winter indoor season, but was always stone-walled. For several years, his Rowdies and several other teams used winter indoor "friendlies" as part of their training and build-up to the outdoor season. In the meantime, pressed by the rival Major Indoor Soccer League (MISL), which inaugurated play in 1978, two-day mini-tournaments like the Skelly Invitational and the NASL Budweiser Invitational were held with varying degrees of success. The NASL finally started a full indoor league schedule, a 12-game season with 10 teams, in 1979–80. For the 1980–81 season, the number of teams playing indoor soccer increased to 19 and the schedule grew to 18 games. The schedule remained at 18 games, but the teams participating decreased to 13 for the 1981–82 season. The league canceled the 1982–83 indoor season and three teams (Chicago, Golden Bay, and San Diego) played in the MISL for that season. Four other teams (Fort Lauderdale, Montreal, Tampa Bay and Tulsa) competed in a short NASL Grand Prix of Indoor Soccer Tournament in early 1983. The NASL indoor season returned for 1983–84 with only seven teams but a 32-game schedule.

Answer: Dallas and Rochester
