There were two versions of Bowling For Dollars in DC, the first won was on WDCA 20 with Don Scott hosting, done from a bowling establishment in Falls Church, then Brunswick River Bowl. Later there was one on WTTG with Johnny Holiday as host from River Bowl, which was the nearest tenpin establishment to me.
In the Twin Cities... 2 strikes for jackpot, 3 for a new dishwasher, and 4 for an OMEGA watch. On the NYC version... 2 for the jackpot, 3 for a trip(in one case, it was Monte Carlo), and 4 for a new Chevrolet vehicle.
